Abstract

In studies of the structure and dynamics of biomacromolecules, Mossbauer absorption spectroscopy (MAS) and Rayleigh scattering of Mossbauer radiation (RSMR) have the advantage of being able to simultaneously extract information about the mean square amplitudes and time correlations of the motion of atoms. The Mossbauer spectra of macromolecules are significantly influenced by the temperature and hydration [1]. The interpretation of this influence is difficult and is most often based on model representations of the macromolecule dynamics. In this contribution we propose a simple physical model of the thermal motion of particles constituting the macromolecule. The model is used to describe the dependence of the MAS and RSMR spectra on the degree of globule hydration.
