The course "Fluctuations and Dynamics of Molecules in a Condensed Environment" deals with the thermodynamic and statistical theory of fluctuations and experimental methods of studying (neutron and optical) dynamics of molecules in a condensed environment. The goal of studying the discipline is to acquire systematic knowledge of the thermodynamic and statistical theory of fluctuations and to master the basics of optical and neutron methods of studying fluctuations and dynamics of molecules in a condensed medium. The educational task of the course consists in mastering the methods of studying fluctuations and dynamics of molecules in a condensed medium.
