Photofragment angular distributions for HF dimer: Scalar J–J correlations in state?to?state photodissociation
Photofragment angular distributions have been measured for HF dimer which show resolved structure that can be assigned to individual fragment rotational channels. This data is used to establish intermolecular scalar correlations between the rotational states of the two HF fragments. The observed angular distributions are strongly dependent upon whether the ‘‘free’’ or ‘‘hydrogen bonded’’ HF stretch is initially excited. Since the infrared spectrum of the parent molecule is highly resolved, these results can be used to determine the relative state?to?state photodissociation cross sections. In addition, the zero point dissociation energy (D 0 ) of the HF dimer is accurately determined.
