Frequency Shift of Acoustic Oscillations of the Tobacco Mosaic Virus with Varying Suspension Parameters

Abstract

When low-frequency stimulated Raman scattering (SRS) is excited in the tobacco mosaic virus (TMV) suspension, an anomaly in the scattering line frequency shift is detected, i.e., the dependence on the concentrations of TMV and tris-buffer as the TMV concentration increases. An explanation of the phenomenon, based on the idea of the formation of the hydration shell of the virus capsid is proposed.
