Abstract

A novel method of measuring the electrically induced dichroism of macromolecular solutions is described. Transient changes in the solution absorption are recorded when the solute molecules are aligned by pulsed electric fields that are applied along the incident path. Previous methods have applied fields transverse to the optical beam which has had to be variably polarized. The present longitudinal arrangement needs no polarizer, is simpler, can yield the required information in a single suitable measurement, and has other distinct advantages over the former transverse arrangements. The theory for the effect is derived, and the interrelation of these novel longitudinal measurements with the conventional transverse data is verified by measurements on an aqueous solution of the amylose triiodide complex.
