IR absorption spectra of proteins, ribonucleic acids and virions of spiral (tobacco mosaic virus) and spheric (carnation mottle virus) types were investigated. Such spectral parameters as total number of bands, their frequency grouping, intensity, half width and frequency characteristics of Amide A, Amide B, Amide 1, Amide 2, Phosphate 1, Phosphate 2 etc. are close enough both for the whole viral nucleoproteins and for their biochemical components. Together with this, convincing differences are observed. Thus, it is possible to differentiate virions- and their constituent biopolymers after their IR spectra. Changes in parameters of the investigated spectra with humidity were found, as well as the stability with temperature decrease to 80 K.
