Abstract

Products of the strengths times the self-broadened half-widths of eight lines in the ν₂ band of water vapor were obtained by the curve of growth method. The experimental conditions were room temperature (300°K), low pressure (0.5–2.2 torr), long path length (1.98 cm × 10⁴ cm), and an observed resolution of ≈0.5 cm⁻¹. Corrections for the absorptance from overlapping of near lines, for the neglected wing absorptance of the main line, and for the absorptance due to wings of distant lines were made using the Lorentz profile and the results of previous theoretical calculations. The results are generally higher than those previously reported.
