Photofragment Spectrum of Bromine,
Abstract
The authors have measured the photofragment spectrum of Br2 at visible and near uv wavelengths using the absorption of a single photon to probe ungerade states and double photon absorption to probe gerade states invisible in the ordinary absorption spectrum. In these experiments a pulsed polarized laser beam intersects a molecular beam in a vacuum chamber and Br atom photodissociation fragments are detected with a mass spectrometer as a function of the angle between the light polarization direction and the recoil path of the detected atoms. They have also found double photon dissociation processes involving absorption of one 18 780 and one 9390/cm photon as well as such processes involving two 18 780/cm photons. Calculations, following Mulliken, of the approximate vertical energies of the newly observed final dissociative states in these double photon processes are in accord with experimental observations.
