Notes:
Equations previously developed for the light scattering of polar chain polymers subjected to orientation by an electrical field are extended to the case where the elementary dipoles have arbitrary direction with respect to the chain contour. As an illustration of the theory, measurements were made of the light scattering of nitrocellulose solutions as a function of the angle of observation, the field strength, the direction of the field, and the frequency of the field. The principal results obtained were: the molecules are deformed by the electrical field; orientation is due primarily to a permanent electric moment whose component per chain segment is of the order of 4 Debye; and the relaxation times for molecular orientation are of the order of magnitude predicted by the theory of Stockmayer and Baur.
