Effects of molecular rotation and vibration--rotation interaction on collisionless multiple-photon excitation of SF/sub 6/
The effects of molecular rotation and vibration--interaction and thermally excited vibrational states on the collisionless multiple-photon excitation (CMPE) of SF/sub 6/ are calculated numerically, using preliminary vibrational anharmonic parameters derived from recent spectroscopid data. This is the first calculation of CMPE in SF/sub 6/ employing the rotational energy levels and transition moments appropriate for a spherical-top molecule. Our calculated multiphoton threshold for CMPE in SF/sub 6/ is lower by orders of magnitude than the threshold calculated without rotations. We have also made a tentative assignment of one transition in the ..nu../sub 3/..-->..2..nu../sub 3/ spectrum of SF/sub 6/.
