Abstract:

The intensities of the individual rotational lines of the A-delta - X-sq pi 0,0 band of CH have been computed by solving the steady-state equations which describes the fluorescence of CH in comets. These intensities are entered in a computer program for producing theoretical profiles which are then compared with the profile observed in the spectrum of Comet Ikeya 1963a. As in the case of CN it is possible to reproduce the observed intensity distribution when the effects of the Fraunhofer lines are properly taken into account. In order to show this the correct intensity factors appropriate to the A-delta - X sq pi transition of CH have been calculated and are given explicity. The pure rotation transition probability for the transition from K 2 to K 1 is found to be about 0.01sec. Author
