DOI: 10.1021/acsnano.4c16535
Abstract: In surface-enhanced Raman scattering (SERS), vibrations of molecules couple with optical modes of a plasmonic nanocavity via a molecular optomechanical interaction. This molecule-plasmon coupling gives rise to optomechanical effects such as vibrational pumping–the excitation of… read more here.

DOI: 10.1103/physrevlett.123.153001
Abstract: Infrared (IR) spectroscopy of molecular vibrations provides insight into molecular structure, coupling, and dynamics. However, picosecond scale intermolecular and intramolecular many-body interactions, nonradiative relaxation, absorption, and thermalization typically dominate over IR spontaneous emission. We demonstrate… read more here.

DOI: 10.1126/sciadv.adv5220
Abstract: Chirality-induced spin selectivity (CISS) encompasses phenomena such as magnetoresistance and enantiomer separation using ferromagnets. It has recently received notable attention. Despite this growing interest, the microscopic mechanisms driving CISS remain a subject of intense debate.… read more here.

DOI: 10.1177/00037028211036509
Abstract: 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… read more here.
