Abstract

In a previous work1, we have put forth the thesis that the experimentally observed2, 3, 4 rapid absorption of several CO2 photons of like frequency, is due to the vibrational octahedral splitting of the vibrational states of overtones of the triply degenerate v3 mode. Up to this point, all other treatments of collisionless multiple-photon dissociation of SF6 by CO2 laser radiation 5, 6, 7, 8, 9, 10, 11, 12 have utilized a simple one dimensional anharmonic oscillator (or equivalent) model for the vibrational states of SF6. In such a model, a fundamental difficulty is immediate: how is the rapid absorption of 25–30 laser photons of approximately like frequency possible, when the (strong) anharmonicity of the molecular potential shrinks the spacing of successive Work performed under the auspices of the United States Energy Research and Development Administration vibrational states too rapidly and by too large an amount? Several explanations have appeared on the scene.
