Stimulated Raman scattering in suspensions of alternanthera mosaic virus and potato virus X in the frequency range of 1–15 GHz

Low-frequency stimulated Raman spectra in suspensions of Alternanthera mosaic virus and Potato virus X are calculated and measured. The discrepancy between the calculated and measured frequencies of the Raman lines for the Potato virus X is attributed to the difference in the mechanical properties of the viruses, in particular, Young's modulus, in the native environment and when measured with an atomic force microscope. Differences are recorded in the stimulated Raman spectra of these viruses, allowing them to be identified.
