H atom elimination from the pi sigma* state in the photodissociation of phenol.
Photodissociation of phenol at 248 nm was studied using multimass ion imaging techniques. Photofragment translational energy distribution of H atom elimination was measured. The results demonstrate that H atom elimination occurs on the pi sigma(*) excited state which has repulsive potential-energy functions with respect to the stretching of OH bond. It supports the recent ab initio calculation.
