Abstract

The total absorptance ∫ A(ν) of water vapor in the vicinity of its vibration-rotation bands near 5332 3700, and 1595 cm−1 has been determined as a function of absorber concentration w and equivalent pressure Pe for pure water vapor samples and samples of water vapor mixed with nitrogen. The present results, together with previously published results of Howard, Burch, and Williams, are presented in graphical form; logarithmic plots give ∫ A(ν) for various values of Pe as a function of absorber concentration w. These plots may be used in estimating total absorptance of water vapor in any sample for which w and Pe are known, and they may be applied in atmospheric studies.
