TEMPERATURE DEPENDENCE OF THE ABSORPTANCE OF AMMONIA NEAR 850/CM.
Abstract
The equipment and experimental techniques used to observe the temperature dependence of absorptance in a small region of the 950/cm band of ammonia are described. The integrated absorptance of two spectral lines was measured at 214K and 300K for samples of pure ammonia and samples of ammonia broadened with nitrogen. The results are presented as plots of total absorptance for the small spectral region versus absorber concentration u and total pressure P. An equivalent pressure Pe is expressed in terms of a self-broadening coefficient B which is function of the ratio of the optical collision diameters. Self-broadening coefficients are determined at 214K and 300K. Integrated absorptances at 300K are compared with those obtained for samples at 214K to determine whether the temperature dependence is that predicted by the Lorentz theory. (Author)
