The dynamic parameters of liquid crystal (LC) systems in liquid crystalline and solid phases, such as orien¬ta¬tion relaxation time and ordering of molecules, were studied by ESR technique with the help of spin probe. It was determined that, depending on the LC system, the rotatory diffusion correlation time (τ_(c )) changes in the same way as the rotational anisotropy. For investigated LC systems in liquid state 10^(-11)<τ_c<10^(-9 ) sec was found. In a frozen LC system, depending on the particular molecular structure of the system’s component, the high molecular mobility of τ_(c )=10^(-9) sec was managed to obtain. It’s shown that such a high mobility of molecules, far beyond the LC→Crystal transition point, is caused by the structural features of component’s molecules that lead to an increase in system polarity and changes in the activation energy for rotational motion of molecules.
