Symmetric breathing mode
WebRaman spectroscopy is the inelastic scattering of laser photons, by excitations such as symmetric breathing modes in molecules or phonons in crystalline solids. We are measuring the loss (or gain) in photon energy upon the creation (or annihilation) of such an excitation. These energies are typically ≈ 100 meV.

WebJan 11, 2024 · For the latter case of transverse modes (fig. 1(b)), of which the simplest is the spherically symmetric breathing mode [49,53], the collective mode spectrum shows a distinct dip in frequency when the inner surface is created. Breathing modes localize near the new boundary as the condensate begins to hollow. WebFor the symmetric breathing mode one has thewell-known result C 22 1=2, which reflects the strong density perturbation by the cross sectional breathing. This allows increasing (hence intensity) by a factor of 2 compared with the correspond-ing single-particle resonance condition n 2; for the quadrupolar mode the coefficient is only 3=4, hence an

WebJan 16, 2024 · Indeed, each vibrational mode of the isolated molecule combines into several modes of different symmetries and frequencies in the crystal, as the unit cell contains four molecules. We focus our attention on the HS symmetric and anti-symmetric breathing modes in the crystal as well as on the N-CS stretching modes.
