Abstract

Starting from different fine structure levels in the metastable c³II_u^- triplet state of molecular hydrogen, we excite ro-vibrational levels in the n equals 3 triplet gerade complex. The linear polarization of the laser results in an alignment of the molecular plane with the polarization vector. This is then reflected in an anisotropy of the photofragments. We show that the anisotropy parameters are influenced by the presence of the electron spin, which causes the fine structure splitting. We compare our results to theoretical expressions for the anisotropy parameter which incorporates the fine structure of the initial and final states.
