STUDIES OF INFRARED RADIATIVE TRANSFER IN HOT GASES. I: SPECIAL ABSORPTANCE MEASUREMENTS IN THE 2.7-MICRON H2O BANDS.

Abstract

Measurements of spectral absorptances in the 2.7-micron water vapor bands were made at moderate resolution, for pressures from 50 mm to 1 atm, temperatures from 750 to 1300 K, and path lengths of 7.75 and 60.0 cm. Samples of pure water vapor were contained in quartz cells heated in a furnace which was built into a specially designed double-beam spectrometer. The resultant spectra are presented and correlated with those obtained by other investigators. Values of a strong-line parameter and a mean line strength for use in nonisothermal radiance calculations were determined. (Author)
