Abstract
Self-broadened linewidths and pressure-induced frequency shifts of N2O were measured from spectra obtained at high spectral resolution in th e 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 val ues of J. Line-strength measurements were derived from spectra obtaine d at low sample pressures, and these data were analyzed to determine v ibrational band strengths, rotationless dipole-moment matrix elements, and F factor coefficients for several bands in the 900-3600 cm(-1) re gion. Measurements of over 15,000 selected vibration-rotation transiti ons, including eight N2O isotopic species, were used in the various an alyses.
