Theory of Twisted Stiff Chains. II

Abstract

A general continuous model of the twisted stiff chain defined by an anisotropic deformational energy density is given and the previous results as for the spatial correlation function of the unit tangential vector of the continuous limit model of a chain composed of hindered-rotating bonds with fluctuating bond angles are regained in the present model. The Yamakawa-Fujii’s helical wormlike chain model based on a space curve is shown to be a special case of the present one.
