The present review of the theory of transport processes in liquids is confined to considerations of the primary molecular mechanism involved in these processes. Thus the questions of irreversibility of nonequilibrium systems in general and of the reciprocal relations among the transport coefficients in coupled processes are not developed. Also in the interest of brevity, the special problems of binary and thermal diffusion are not dealt with in detail. This being a review of theory, there is no attempt to present the numerous experimental studies of transport processes in various liquid systems in the past decade. 

Samulski et al2D suggested that an asymetric helical molecular conformation may provide an explanation for the cholesteric structure, and very small oscillations of helices relative to their neighbors in the liquid crystal would be biased to one side of the parallel position because of the chirality of the van der Waals surface of the polypeptide molecules. Further, they found a linear relationship between the pitch and the reciprocal of temperature. This relation holds quite well for a number of thermotropic liquid crystal systems and was explained theoretically by Keating ), who treated the macroscopic twist as a rotational analogue of thermal expansion with the dominant anharmonic forces coming from nearest neigh-...
