“…It also enhances low-frequency Raman bands, such as stimulated Brillouin scattering (SBS) in which the vibrational mode is a phonon mode. SBS has been observed with a Fabry–Perot interferometer to resolve small wavelength differences in intense Rayleigh scattering, and it has been applied to the intermolecular structure and dynamics of various liquids. − Low-frequency SRS has recently been used for the analysis of nanoparticles in liquids. − …”

Low-frequency intermolecular motions are of importance for understanding the structure of molecular liquids, which can be elucidated by Raman spectroscopy. A liquid droplet provides a field where stimulated Raman scattering (SRS) readily proceeds. Our previous study showed that multiorder SRS is more effectively generated in colliding droplets than a single droplet. Here we report that the multiorder SRS generated in colliding benzene droplets included lowfrequency bands of the liquid benzene, which is considered to represent a temporal state of liquid emerging in the course of the droplet collision. This method enables measurements of the low-frequency intermolecular motions of the novel liquid state emerging at the mixed region of the colliding droplet without suffering from background of Rayleigh scattering.

“…It is connected with virus vibration damping due to the radiation of the acoustic energy in environment [17]. One other way to obtain information about the frequency of the acoustic vibrations of a nanoparticles system, including viruses, may be the process of stimulated lowfrequency Raman scattering (SLFRS) [18][19][20]. SLFRS is a stimulated analogue of low-frequency Raman scattering which was realized for large number of nanoparticles of different natures.…”

The interaction of laser pulses with the Cauliflower mosaic virus (CaMV) in a Tris-HCl pH7.5 buffer is investigated. 20 ns ruby laser pulses are used for excitation. Spectra of the light passing through the sample and reflected from it are registered with the help of a Fabri-Perot interferometer. Stimulated low-frequency Raman scattering (SLFRS) in a CaMV suspension is registered. The SLFRS frequency shift, conversion efficiency and threshold are measured for the first time, to the best of our knowledge.
