Abstract
Recent studies of cholesteric systems are briefly reviewed, with special attention paid to the relationship between the molecular structure of the optically active molecules and the helical twisting features. Microscopic models are presented which provide an account of specific intermolecular interactions, conformational equilibria, etc. Mechanisms of dopant-induced helix distortions are discussed based on N.M.R. studies. The use of cholesteric systems as solvents for selective reflection spectroscopy is considered.Keywords
