COMPUTER PROGRAMS FOR ANALYZING HIGH RESOLUTION INFRARED SPECTRA

This research was supported by N.S.F. and A.F.C.R.L.Author Institution: Physics Department, Michigan State UniversityThe infrared spectroscopy group in the Physics Department at Michigan State University has accumulated a number of very useful computer programs written by past and present graduate student members of the group. This paper will describe a number of these programs which fall into three general categories: 1. Programs designed to handle and reduce the spectral data through calibration, averaging and assisting in assigning observed transitions. 2. Programs to predict frequencies and intensities from assumed molecular constants, for comparison with observed spectra. 3. Programs to analyze spectra by least squares fits of combination differences, energy levels, individual bands and combinations of bands of diatomic, axially symmetric and asymmetric rotor-type molecules
