STUDY OF THE LINE-WIDTH IN THE ROTATIONAL SPECTRUM OF METHYLFLUORIDE

The results of a study on the line width in the pure rotational spectrum of methylfluoride are presented. The experimental values of the normalized line width as a function of the line number show a maximum at m = 16. There is good qualitative agreement with the theoretical results obtained with the quantum mechanical theory of Murphy and Boggs, although there remains a discrepancy in absolute value. An important result is that the Murphy and Boggs theory predicts quite accurately the temperature dependence of the line width. © 1979.
