Green's function analysis of the vibrational spectra of polymer chains. II. Fourier method for calculating the green's function of a perfect infinite polymer chain

Abstract

SynopsisA new method of calculating the Green's function (GF) for an arbitrary polymer chain is suggested.It makes it possible to obtain analytical expressions for this function in a number of cases of practical value.The calculation of the Green's function (GF) G(0)(w2) for a perfect system is an important and independent part of the solution of the dynamical equation for disordered solids. As shown in part I of this series,l the GF can be employed
