RESEARCH DIRECTED TOWARD THE STUDY OF INFRARED TRANSMISSION THROUGH VARIOUS ATMOSPHERES.
Abstract
Previously reported work is summarized (see AD-607 401 and AD-638 747), and a detailed report is given concerning further data obtained for ammonia samples at reduced temperatures are presented and used to obtain a self-broadening coefficient relative to helium. Some data in report AD-638 747 indicate a possible temperature dependence of the optical collision diameters; further data is necessary to determine the functional dependence. It appears that the dependence is T exp.-b where b is a small positive number. A prism spectrometer was used with a sampling technique involving a continuous gas flow through the absorption cell to obtain a band strength for the 667/cm band of CO2 which is in agreement with that obtained from high resolution measurements and agrees with the spectral characteristics given by Burch, Gryvnak, and Williams.
