## Abstract A series of step reaction polymers have been prepared and studied as melt films or in solution in the overtone region and the combination region of the near‐IR. Systems containing aryl rings show bands in the 2.13‐ to 2.16‐μm region which are not observed in those systems not having ary

✦ Synopsis
Band analyses of the NIR spectra of two C~o salts in nine solvents reveal a previously unnoticed low-energy transition arising from a thermally populated excited electronic state. The viability of vibronic origin for three intermediate-energy transitions is confirmed. A multiplicity of weak high-energy transitions presently defies unique deconvolution and assignment.

We have recorded a total of 12 FTIR spectra of monoisotopic OC 80 Se in different spectral regions with a resolution (1/maximum optical path difference) between 2.7 and 13.2 ϫ 10 Ϫ3 cm Ϫ1 . These spectra spanned the range from 350 to 7800 cm Ϫ1 , many bands being studied with different p ϫ L product

## 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
