[The effect of time-relaxation spectral width on temperature dependences of parameters of Mossbauer spectra of biopolymers].
A new model for description of dynamic properties of macromolecule, especially globular proteins, is proposed. The model proposes the existence of time-relaxation spectra determining the time characteristics of biomacromolecule dynamics. The time dependence of mean-square deviation of atom from the initial state and spectra of Rayleigh scattering of Mossbauer radiation (RSNR) have been calculated. The temperature dependence of model spectra properties has been investigated. It has been shown that with the increase of time-relaxation spectra range of macromolecules the square under RSNR spectra with temperature growth decreases more quietly. It has been concluded that the idea concerning the time-relaxation spectra existence doesn't explain the sharp decrease of square of protein experimental spectra.
