Far-infrared spectra in the region from 700 to 200 cm-l were measured for the copolymers of calanine and glycine, those of calanine and L-valine, those of calanine and L-leucine, and those of L-alanine and cphenylalanine. The observed spectra were interpreted on the basis of the analysis of the far-
## Abstract The absorption spectra of a series of polyamic acids prepared using various reaction conditions were studied using the ultraviolet (UV), visible, and near‐infrared (IR) ranges. The near‐IR proved most valuable; the amidization and imidization processes could be followed by observing the
