Investigations of Chemical Laser Processes
Abstract
A complete set of electric dipole transition probabilities for HCl has been computed by means of a numerical procedure developed previously. To produce these computations, the dipole moment and internuclear potential for the HCl molecule were modeled with the available experimental data. The results are presented in tabular form for vibrational quantum states from 0 to 12, for changes in vibrational states between 0 and 5, and for all rotational states between 0 and 35. Progress on experimental measurements of the intensity of the v = 0 to v' = 4 band of CO are included as well as progress on an experiment to measure rotational relaxation in an excited cell of HF. Measurements of the strengths and widths of lines in the v = 0 to v' = 3 band of HF are reported. This work was begun under an earlier contract with the Advanced Research Projects Agency, and was completed under the current contract. The electric dipole matrix element for the band has been determined from the measured strengths to be 1.628 x 10 to the minus 21st power esu-cm. The rotational dependence of the measured half widths agrees with the Anderson theory of collision broadening if off-resonant collisions are taken into account. A complete code has been written to compute line widths resulting from collision broadening. A section describing this program is included. Sample calculations which show good agreement with available experimental data are presented.
