Pressure Broadening of DCl by HCl and of HCl by DCl. A Comparison of Experimental Results with Anderson's Theory

Linewidths in the 1–0 band of DCl broadened by HCl and in the 1–0 band of HCl broadened by DCl are reported for rotational levels up to | m | = 15 and 13, respectively. These experimental results are compared with calculated values using Anderson's theory as amplified by Tsao and Curnette. Calculations are made at 300°K for quadrupole moments of 2, 4, and 6 D·Å and calculations at 194.5°K are also made for a Q of 6 D·Å.
