PHOTOFRAGMENT SPECTROSCOPY OF DISSOCIATIVE EXCITED STATES,

Abstract

A new form of molecular spectroscopy was developed to study dissociative excited electronic states. A molecular beam is crossed by pulses of polarized light and the distribution of recoiling photodissociation fragments is measured by a mass-spectrometer as a function of energy of the photons, mass of the fragments, translational energy of the fragments, and angle of fragment recoil with respect to the polarization direction. In experiments with a variety of molecular transitions it is shown that such information as the transition moment direction, the upper state symmetry, the identification of the fragments and their internal states, the bond strengths and the molecular dynamics of dissociation may be deduced from this multi-dimensional distribution.
