Abstract
The thermal relaxation absorption in the deuterated methanes has been obtained by the tube method for frequencies between 20 and 640 kc/sec·atm. The relaxation time, transition probability, and collision efficiency were determined for each gas. The collision efficiency as a function of molecular weight has been found to follow a simple relation of the form: P10∝[M]−½.Keywords
