Abstract

Self-broadened linewidths and pressure-induced frequency shifts of N2O were measured from spectra obtained at high spectral resolution in the 1800–2630 cm−1 region. From measurements of 136 lines, the average pressure-shift coefficient was found to be −0.0015 ± 0.0006 cm−1/atm. The shift coefficients were found to have a weak J dependence, in which the magnitude of the coefficients increases with increasing values of J. Line-strength measurements were derived from spectra obtained at low sample pressures, and these data were analyzed to determine vibrational band strengths, rotationless dipole-moment matrix elements, and F factor coefficients for several bands in the 900–3600 cm−1 region. Measurements of over 15,000 selected vibration–rotation transitions, including eight N2O isotopic species, were used in the various analyses.

Several perturbed transitions are displayed showing unapodized spectra covering the interval from 3496.9 to 3513 cm−1 in which R-branch lines of the 0600–0000, 0620(e)–0000, 0730(f)–0110(f), and 0710(f)–0110(f) bands of 14N216O are noted with four different symbols: ○ for the 0600–0000 band, ● for the 0620(e)–0000 band, △ for the 0730(f)–0110(f) band, and ▲ for the 0710(f)–0110(f) band. The observed spectra are overlaid with the respective synthetic spectra in the eight plots. The residue plot, shown above each spectral portion, gives the percent difference between the observed and computed spectra. The eight displays also include hash marks located above spectral features that represent the lines included in the synthetic spectra. The spectrum from which the figure was made is the run that was recorded with a 433-m path length and a 1-Torr sample pressure.
