Abstract
The general theory of the longitudinal vibrations of a composite perturbed elastic rod has been applied to the observed LAM frequencies of n‐paraffins, a cyclic paraffin, and polyethylene. The good agreement obtained between observed and calculated results shows that force and mass perturbations at the chain ends have a significant, and non‐negligible, effect on the LAM frequency.This publication has 21 references indexed in Scilit:
