Mechanisms of Multiphoton Dissociation of Molecular Ions.

Abstract

The dissociation of highly vibrationally excited molecular ions resulting from single infrared photon absorption has been studied. The wavelength dependence of the absorption/dissociation process has been measured, and the photofragments identified. Measurements were also made of the dissociative lifetime following absorption and the photofragment kinetic energy distributions. These measurements show that a strong correlation exists between this single photon dissociation process and the final step of multiphoton dissociation. Based on these results, the dissociation dynamics appear to follow a single statistical mechanism. (Author)
