Angular correlations in linear copolymers from the compositional dependence of their dipole moments. II. Markovian typal sequences

Abstract

An earlier treatment of the problem of extracting configurational information from experimental determinations of the compositional dependence of the dipole moments of copolymers containing random sequences is extended to include the case wherein typal correlations arise from pair dependent probabilities for the occurrence of the structural units in the copolymer. If the typal correlations are sufficiently strong, it is possible to evaluate certain, meaningful, linear combinations of terms containing the average cosines of the angles between the dipole moments of nearby pairs of structural units, as well as the angular correlation length M, measured by the number of structural units beyond which the average cosines are negligible. Conditions are given in order to be able to separate and evaluate the average cosines belonging to individual pairs of structural units.
