On the Dynamics of Multiphoton Dissociation of Polyatomic Molecules II. Application to O₃

Abstract

A knowledge of the level structure of polyatomic molecules is essential to an understanding of the col 1isionless dissociation of polyatomic molecules by infrared radiation [1] As a quantum mechanical calculation of the higher levels of polyatomic molecules is impossible because huge basis sets would be required, recourse has to be made to semiclassical [2] or classical methods [3]. We have chosen to use, and have further developed a classical method given by NOID et al. [3], [4] which permits direct calculation of the molecular spectra. When the laser field is included in thè model dissociation probabilities and energy distributions may also be calculated [5], [6], [7J. In the following the method used will be outlined, briefly. In §2 and §3 an application to a model of O₃ will be given.
