QUANTITATIVE HIGH TEMPERATURE INFRARED SPECTROSCOPY.
TECHNION - ISRAEL INST OF TECH HAIFA DEPT OF PHYSICS
Spectral emissivity studies were made of the three water vapor bands at 1.9, 2.7 and 6.3-microns. Atmospheric interference was successfully eliminated by building a hermetically sealed optical system, from which absorbing gases could be eliminated. Spectral studies with a resolution of 0.5cm were carried out for H2O vapor at 1200K in the 1.9 and 2.7-microns bands. By the use of spectral band models the band parameters and the integrated intensity of these two bands were determined at 1200K. The method of curves of growth was also applied to atmospheric absorption by CO, N2O and H2O at room temperature. Total emissivity calculations were made on H2O at 1200K, based on the contributions of spectral band emissivities in the 1.9, 2.7 and 6.3-microns regions. The integrated intensity of the 6.3-microns band was established by measuring the intensity of a single rotational line in this band. Author
