Abstract

The collision-broadened linewidths and band intensities of three overlapping CO₂ bands near 2600 cm⁻¹ have been determined from spectra obtained with a Fourier transform spectrometer. These spectra have SNRs in excess of 500 and a spectral resolution of ~0.06 cm⁻¹. Calculated spectra were matched to the observed spectra by nonlinear least squares regression over 100-cm⁻¹ intervals. More than forty parameters were estimated simultaneously, and the mean differences between the spectra were about one and a half times the mean noise in the experimental spectra.
