Abstract
Molecular photoionization and (photo-)dissociation dynamics both result, in general, in anisotropic fragment spatial distributions reflecting the non-spherical potentials experienced in these processes. In dissociative photoionization events, where two such nominally sequential fragmentations take place, the photoelectron and photofragment ion recoil directions can be mutually correlated. It is demonstrated how this correlation may be exploited to select both the state and effective orientation of an ensemble of symmetric top molecular ions. The feasibility of this orientational selection is explored both with model calculations of the photoelectron angular distributions resulting from ionization of partially oriented molecules and with experimental photoelectron-ion coincidence measurements.
