Abstract

A generalized theoretical model to interpret the orientational relaxation in uniaxially aligned systems is suggested. The proposed approach is more general than those existing so far, which can be derived from our approach as particular cases at a constant residence time. It is compared with the results obtained by strong collision and small step rotational diffusion models..
