The absorption spectrum of water vapor has been studied quantitatively with a resolution of approximately 0.12 cm-1 between 475–692 cm-1. Several methods of extracting the intensity and line-width parameters from the measurements on 19 well-resolved lines are compared and discussed. The intensities show deviations from those calculated for a rigid asymmetric rotor, which are attributed to effects of centrifugal stretching. Half-widths are presented for H2O-H2O, H2O-N2, H2O-CO2, and H2O-He broadening at 80°C and for H2O-air at 24°C.
