Pressure dependence of the water vapor continuum absorption in the 3.5-4.0-microm region.

A line tunable deuterium fluoride laser was used to measure the pressure dependence of the water vapor continuum absorption at 25 degrees C in the 3.5-4.0-microm spectral region. From measurements of the absorption of 14.3 Torr of deuterium depleted water vapor buffered by several air-broadening pressures, an unexpectedly small foreign-to-self-broadening coefficient of 0.011 with a factor of 2 uncertainty as well as an unusually strong self-contribution for the water vapor continuum absorption were observed. These measurements can be used to infer contributions to the water vapor continuum in the 3-5-microm window from both far wing and aggregate-water-molecule type absorptions.
