Abstract

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.
