SPECTRAL EMISSIVITIES AND INTEGRATED INTENSITIES OF THE 6.3-MICRON FUNDAMENTAL BAND OF H2O

Abstract

Spectral emissivities of the v2-fundamental band of water have been measured between 550 and 2200 K. The hot water vapor samples were produced in a small supersonic burner using H2 and O2 gases. The variation of the spectral emissivities of H2O as a function of temperature has been obtained for a constant amoung of H2O in the optical path. An estimate of the integrated intensity of the 6.3-micron fundamental band has been made from the high temperature emission spectra. The observed integrated intensity of the 6.3- micron H2O band was 300=20 per cent (1/cm sq. atm) at 273 K and is independent of the temperature.
