Molecular vibrational imaging at nanoscale

The Journal of Chemical Physics, 2022
The demand to visualize the spatial distribution of chemical species based on vibrational spectra is rapidly increasing. Driven by such a need, various Raman and infrared spectro-microscopies with a nanometric spatial resolution have been developed over the last two decades. Despite rapid progress, a large gap still exists between the general needs and

Vibrational molecular microspectroscopy

Analytical Chemistry, 1986
General identification of compounds at the picogram level can now be accomplished through the techniques of molecular microspectroscopy, i.e., molecular spectroscopy through a microscope. Although there are many different molecular spectroscopies, the most versatile ones for identification are infrared (IR) and Raman spectroscopies.

Molecular Vibrations Are Not Asymmetric

Applied Spectroscopy, 2021
There is considerable confusion when naming vibrations in infrared and Raman spectra. One of the most common errors is the identification of some stretching and bending vibrations as “asymmetric”. There are no asymmetric vibrations as such vibrations incur rotations and translations.

Interaction Terms in Molecular Vibrations

Nature, 1947
We have recently been investigating the magnitudes and signs of the interaction terms in the potential functions of triatomic molecules XYZ. These arise from interactions between two bond-lengths (XY and YZ), or between one bond-length and the angle XYZ. In our study of these terms we have distinguished three distinct effects: (1) resonance effects; (2)
