This article is an overview of advances in Raman spectroscopy published in 2019 in the Journal of Raman Spectroscopy (JRS) and, in addition, trends over the past decade across journals that have published papers important to the field of Raman spectroscopy. The trends are based on statistical data of article counts obtained from Clarivate Analytic's Web of Science Core Collection by year and by subfield of Raman spectroscopy. Normally in this review, coverage would be provided for presentations involving Raman Spectroscopy at the following four international conferences previously scheduled for this year: the International Conference on Raman Spectroscopy (ICORS 2020) in Rome, Italy; SCIX 2020 organized by the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS) in Reno, Nevada, USA, in October; the European Conference on Nonlinear Optical Spectroscopy (ECONOS 2020) in Karlsrue, Germany, in April; and the International Conference on the GeoRaman Spectroscopy (GeoRaman 2020) in Bilbao, Spain, in November (originally scheduled for Weihai, China, in June). Of these, the ICORS 2020 has been rescheduled for 2021 at the same location; ECONOS 2020 has been canceled, but instead, a special issue section is being organized by invitation to commemorate the passing of JRS Board member Marcus Motzkus; SCIX 2020 has been changed to a virtual online conference; GeoRaman 2020 has been canceled, but online submission of abstracts will be made available with selected invitations to submit papers for a special issue of JRS. Finally, papers published in JRS in 2019 are highlighted and arranged by topics at the frontier of Raman spectroscopy. Based on these data, presentations, and publications, it is clear that Raman spectroscopy continues as an expanding field of research across a wide range of novel disciplines and applications that provide sensitive photonic information at the molecular level.
