The F–P cavity and schemes of various frequency regimes. (a) Schematic illustration of standing-wave like photon modes (2nd order, as an example here) in a Fabry–Pérot cavity, where the transmission peaks of various F–P cavity modes is shown as the black spectrum. (b) Molecular vibrational dynamics, such as Berry pseudorotation and intramolecular vibrational redistribution (IVR), can be modified by VSC, in the IR-regime cavity.
