LINE STRENGTHS (900-3600 CM(-1)), SELF-BROADENED LINEWIDTHS, AND FREQUENCY-SHIFTS (1800-2360 CM(-1)) OF N2O

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.
