Abstract
The photodissociation is an important elementary process in the interaction of light with molecules. In the investigation of the dynamics of the photodissociation special attention has been directed to the question how the excess energy is distributed among the dissociation products and among their different degrees of freedom. The excess energy is the difference between the dissociating photon energy and the necessary dissociation energy of the molecule. One of the most successful experimental attempts for clarifying these questions is molecular beam photofragment spectroscopy with mass spectrometric time-of-flight fragment detection [1,2], This method is generally applicable and yields inter-fragment recoil and momentum distributions. Quantum state specific measurements are normally not possible because of limitation of the velocity resolution. With this method the dissociation of NO2 into NO and O has been previously investigated by Busch and Wilson [l] at λ = 347 nm. The translational energy resolution achieved was about 200 cm-1. A theoretical interpretation of their results has been given by Quack and Troe [3] assuming a statistical distribution of the excess energy.
