Dynamics of macromolecular chains. I. Theory of motions on a tetrahedral lattice

Abstract

Abstract The bond correlation function for a macromolecular model chain on a tetrahedral lattice is derived by considering elementary three‐bond and four‐bond motions. The method of calculation allows the conformational structure of the chain to be involved in the final equations. Moreover, when the three‐bond motions are considered alone, no linearization assumption is required; hence, the theory is valid at short times.
