Whole-band analysis of infrared spectra of nitrous oxide broadened by nitrogen, oxygen, and air

OSTI ID:5018308
Spectra of the 12/sup 0/0 and 13/sup 1/0-01/sup 1/0 bands of nitrous oxide at 2450cm/sup -1/ have been analyzed by the nonlinear least-squares, whole-band analysis technique. Relative line intensities, and nitrogen-, oxygen-, and air-broadened line widths were measured. The results indicate that the air-broadened line widths in the 1981 AFGL line listing are correct for /m/>4 but too low for /m/<4, and that published calculated values for the oxygen-broadened widths are low by about a factor of two. The influence of instrumental effects, such as phase error, finite aperture size, and channel spectra, on the observed spectra and on the retrieved line intensities and widths, was also examined.
