Abstract
A rigorous theoretical connection is established between experimental measurements of the photofragment orientation and alignment and the underlying photodissociation dynamics. Laboratory and molecular-frame angular momentum state multipoles are derived as a function of photofragment recoil angles. These state multipoles are expressed in terms of orientation and alignment anisotropy parameters, which contain information on excited state symmetries, coherence effects, and nonadiabatic interactions. To demonstrate the power of our theoretical method, it is applied to experimental data obtained with velocity map ion imaging and Doppler techniques in both diatomic (RbI and Cl2) and polyatomic systems (NO2 and N2O). Strong recoil-frame alignment and orientation has been observed, as well as coherence effects and long-range nonadiabatic interactions.
