Abstract
Theoretical formulas are derived for the angular distribution of photo-dissociated fragments via higher-order processes. These will be contrasted with those for the lowest-order one-photon and electric-dipole induced dissociation of a diatomic molecule for which the angular distribution is a function of the angle between the transition dipole moment and the principal molecular axis. Angular factors for higher-order dissociation will depend on the symmetry of the initial and final vibronic states of the photo-excitation and on the dissociating state. For $2n{\eta}$-pole transition and $\eta$-photon processes, such factors will involve irreducible tensors up to $2_{\eta}{^{th}}$ rank and the corresponding Clebsch-Gordan vector coupling coefficients. They will also incur special vibronic selection rules. The details of these will be discussed.
