Abstract:
A stimulated low-frequency Raman scattering signal with frequencies of about 31.17 and 43.5 GHz caused by the presence of natural vibrational frequencies of the studied tobacco mosaic virus particles is detected in a suspension of the tobacco mosaic virus at the suspension particle concentrations of about 10$^{12}$ and 2.0$\times$10$^{12}$cm$^{-3}$. A change in the suspension temperature at a given concentration of virus particles leads to a significant change in the observed stimulated low-frequency Raman scattering spectrum. The detected coherent signal of the first Stokes component with a frequency shift of about 43.5 GHz is in good agreement with our estimates of the natural vibrational frequencies of cylindrical nanoparticles in a liquid medium.
