Electronic Absorption Spectra and Geometry of Organic Molecules: An Application of Molecular Orbital Theory focuses on electronic absorption spectra of organic compounds and molecules. The book begins with the discussions on molecular spectra, electronic absorption spectra of organic compounds, and practical measures of absorption intensity. The text also focuses on molecular orbital theory and group theory. Molecular state functions; fundamental postulates of quantum theory; representation of symmetry groups; and symmetry operations and symmetry groups are described. The book also discusses shape of absorption bands and geometry of excited electronic states; effect of environment on electronic absorption spectra; and the application of simple LCAO MO method to simple π systems. An evaluation of the parameters used in simple LCAO MO method is presented. The text notes the usefulness and restrictions of simple LCAO MO method in the interpretation of electronic absorption spectra. The correlation between results of simple MO calculation and spectral data in aromatic hydrocarbons, and correlation between results of simple MO calculation and spectral data in conjugated linear polyenes are discussed. The book also looks at MO methods and the relations between electronic absorption spectra and geometry of molecules, biphenyl, styrene, and related compounds. The text is a good source of data for researchers and chemistry students who want to study electronic absorption spectra.

Determination of Organic Structures by Physical Methods, Volume 1 focuses on the processes, methodologies, principles, and approaches involved in the determination of organic structures by physical methods, including infrared light absorption, thermodynamic properties, Raman spectra, and kinetics. The selection first elaborates on the phase properties of small molecules, equilibrium and dynamic properties of large molecules, and optical rotation. Discussions focus on simple acyclic compounds, carbohydrates, steroids, diffusion, viscosity, osmotic pressure, sedimentation velocity, melting and boiling points, and molar volume. The book then examines ultraviolet and visible light absorption, infrared light absorption, Raman spectra, and the theory of magnetic susceptibility. Concerns cover applications to the study of organic compounds, applications to the determination of structure, determination of thermodynamic properties, and experimental methods and evaluation of data. The text ponders on wave-mechanical theory, reaction kinetics, and dissociation constants, including dissociation of molecular addition compounds, principles of reaction kinetics, and valence-bond treatment of aromatic systems. The selection is a valuable source of data for researchers interested in the determination of organic structures by physical methods.

Progress in Physical Organic Chemistry is dedicated to reviewing the latest investigations into organic chemistry that use quantitative and mathematical methods. These reviews help readers understand the importance of individual discoveries and what they mean to the field as a whole. Moreover, the authors, leading experts in their fields, offer unique and thought-provoking perspectives on the current state of the science and its future directions. With so many new findings published in a broad range of journals, Progress in Physical Organic Chemistry fills the need for a central resource that presents, analyzes, and contextualizes the major advances in the field. The articles published in Progress in Physical Organic Chemistry are not only of interest to scientists working in physical organic chemistry, but also scientists working in the many subdisciplines of chemistry in which physical organic chemistry approaches are now applied, such as biochemistry, pharmaceutical chemistry, and materials and polymer science. Among the topics explored in this series are reaction mechanisms; reactive intermediates; combinatorial strategies; novel structures; spectroscopy; chemistry at interfaces; stereochemistry; conformational analysis; quantum chemical studies; structure-reactivity relationships; solvent, isotope and solid-state effects; long-lived charged, sextet or open-shell species; magnetic, non-linear optical and conducting molecules; and molecular recognition.
