This book highlights recent advances of spectroscopic techniques based on Raman scattering. Different applications are introduced that serve as examples for the versatile use of Raman techniques. Raman spectroscopy is a marker free technique, which is capable of yielding detailed information about molecular systems in a non-destructive way. This makes it a valuable tool for, e.g., material science or medical research. The access to vibrational energy and dynamics yields fundamental insights into static and dynamical structural properties of molecules being influenced by and influencing their material science or medical research environment. The better understanding of the basic building blocks of materials helps to improve the functionality in various applications. Raman spectroscopy has become a truly interdisciplinary research tool, and the ongoing development of techniques makes it attractive for growing variety of scientific and industrial applications, which will be demonstrated in the book. While the “classical” linear spontaneous Raman spectroscopy is restricted in its applicability due to low signal intensities or the excitation of strong fluorescence background, new techniques have helped to overcome such problems. Examples, presented in the book, are surface-enhanced Raman scattering (SERS), and various associated techniques are used to drastically increase signal intensity, confocal, and tip-enhanced Raman scattering (TERS) allowing for high and even sub-diffraction limited spatial resolutions, coherent anti-Stokes Raman scattering (CARS) avoiding fluorescence background and allowing for time-resolved observations of vibrational dynamics, or hyper- and resonance Raman scattering influencing the scattering based on electronic resonances, etc.

This book builds a narrative on the near-field optical and spectroscopic studies with an emphasis on plasmonic- and photonic-assisted nano-optics as a tool for superlensing. Deliberations on near-field studies using confined light in various applications are included along with their commercial implications. Single-molecule detection utilizing efficient surface-enhanced Raman scattering phenomenon in the far-field and plasmonic tip-enhanced Raman scattering studies in the near-field measurements for fast analysis up to trace level is discussed.Features: Covers the broad area of nano-optical spectroscopy from the perspective of putting the concepts and innovations in the field to use Discusses entire spectra of near-field optics and spectroscopy using light Explores gas/chemical sensing using surface plasmon resonance (SPR) in the Kretschmann configuration Includes dielectric nano-photonics and optical confinement Studies phonon behaviour using confined light for the analysis of chemical, biological, and other materials This book is aimed at graduate students and researchers in material science, analytical chemistry, nanotechnology, and electrical engineering.

Quite a few excellent books about vibrational spectroscopy have already been published. So why write a new one? The last years have seen the birth of new techniques and, first of all, a wealth of new applications. Therefore, a lot of new users need an introduction to these techniques and applications, but, if they are new to vibrational spectroscopy, an introduction to the parent techniques as well. Vibrational spectroscopies can detect and analyze vibrations in molecules. Mainly two different forms are used today: Infrared and Raman spectroscopy. Vibrational spectroscopy is used by chemists to characterize their substances. If the spectra of substances are known, analytical chemists can use them to analyze a mixture of chemicals. Samples may be analyzed even with spatial resolution, on the microscopic as well as on the macroscopic scale.'Infrared and Raman Spectroscopy'is intended for researchers or lecturers in Chemistry, Physics, Materials Science and Life Sciences, who are interested in the composition and properties of their samples. It describes how vibrational spectroscopy will enable them to examine thin layers, surfaces and interfaces, and also improve their knowledge about the properties of composites. Special chapters introduce VCD, ROA, and TERS. The book can serve as a short introduction to vibrational spectroscopy too, so that students at the first graduate level will benefit from it as well.

This practical and unique textbook explains the core areas of molecular spectroscopy as a classical teacher would, from the perspective of both theory and experimental practice. Comprehensive in scope, the author carefully explores and explains each concept, walking side by side with the student through carefully constructed text, pedagogy, and derivations to ensure comprehension of the basics before approaching higher level topics. The author incorporates both electric resonance and magnetic resonance in the textbook.

Micro-Raman Spectroscopy introduces readers to the theory and application of Raman microscopy. Raman microscopy is used to study the chemical signature of samples with little preperation in a non-destructive manner. An easy to use technique with ever increasing technological advances, Micro-Raman has significant application for researchers in the fields of materials science, medicine, pharmaceuticals, and chemistry.

This book shows the electronic, optical and lattice-vibration properties of the two-dimensional materials which are revealed by the Raman spectroscopy. It consists of eleven chapters covering various Raman spectroscopy techniques (ultralow-frequency, resonant Raman spectroscopy, Raman imaging), different kinds of two-dimensional materials (in-plane isotropy and anisotropy materials, van der Waals heterostructures) and their physical properties (double-resonant theory, surface and interface effect). The topics include the theory origin, experimental phenomenon and advanced techniques in this area. This book is interesting and useful to a wide readership in various fields of condensed matter physics, materials science and engineering.

Spectroscopic Methods in Mineralogy and Material Science covers significant advances in the technological aspects and applications of spectroscopic and microscopic techniques used in the Earth and Materials Sciences. The current volume compliments the now classic Volume 18, Spectroscopic Methods in Mineralogy and Geology, which became an essential resource to many scientists and educators for the past two decades. This volume updates techniques covered in Volume 18, and introduces new techniques available for probing the secrets of Earth materials, such as X-ray Raman and Brillouin spectroscopy. Other important topics including Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM) are also covered.

This thesis identifies the turning point in chain length, after which alkanes self-solvate into a folded structure instead of an extended stretched conformation. After this turning point, London dispersion forces rearrange isolated n-alkanes into a particular hairpin-structure, while for shorter chain lengths, a simple stretched conformation is energetically preferred. This thesis can locate the experimental turning point for the first time in an interaction-free manner from measurements of unbranched alkanes at low temperatures in supersonic jet expansions. It contains a detailed analysis of the vibrational Raman spectra of the chain molecules, which is supported by comprehensive quantum chemical simulations. In this way, the detailed balance between inter-chain attraction and conformational flexibility can be quantified. The investigations are complemented by measurements of perfluoroalkanes and similarities and differences between the compounds are discussed. Furthermore, Nils Lüttschwager determines the stiffnesses (elastic moduli) of two of the most common industrial polymers: polyethylene and polytetrafluorethylene. He uses in this thesis a sophisticated extrapolation to calculate this value from quantities of their building blocks, showing that the single polymer molecules can be as stiff as a rod of steel.

Raman scattering is now being applied with increasing success to a wide range of practical problems at the cutting edge of materials science. The purpose of this book is to make Raman spectroscopy understandable to the non-specialist and thus to bring it into the mainstream of routine materials characterization. The book is pedagogical in approach and focuses on technologically important condensed-matter systems in which the specific use of Raman spectroscopy yields new and useful information. Included are chapters on instrumentation, bulk semiconductors and alloys, heterostructures, high-Tc superconductors, catalysts, carbon-based materials, wide-gap and super-hard materials, and polymers.

Almost 30 years after the first reports on surface-enhanced Raman signals, the phenomenon of surface-enhanced Raman scattering (SERS) is now well established. Yet, explaining the enhancement of a spectroscopic signal by fouteen orders of magnitude continues to attract the attention of physicists and chemists alike. And, at the same time and rapidly growing, SERS is becoming a very useful spectroscopic tool with exciting applications in many fields. SERS gained particular interest after single-molecule Raman spectroscopy had been demonstrated. This bookl summarizes and discusses present theoretical approaches that explain the phenomenon of SERS and reports on new and exciting experiments and applications of the fascinating spectroscopic effect.

Used primarily for characterizing polymers and biological systems, vibrational spectroscopy continues to uncover structural information pertinent to a growing number of applications.
