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 667cm 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.
