Rayleigh scattering of depolarized light from liquid pyridine

Liquid pyridine was investigated by Rayleigh light scattering at a normal pressure, in the temperature range 236–385 K. The function of reorientation G(t), both the first K(t) and the second K(2)(t) memory functions [1], the autocorrelation time, the rotational diffusion coefficient and the activation energy for reorientation have been calculated from the measured depolarized Rayleigh wing. The results are summarized in tables and shown in figures. Molecular dynamics (MD) testing simulations were made to obtain more interesting data on pyridine.
