VUV light photolysis of o-chlorobenzaldehyde (CBA) has been investigated by infrared spectroscopy in cryogenic Ar and O 2 matrices. Previously reported photoinduced rotational isomerization from anti-to syn-CBA was confirmed in the Ar matrix. In addition, absorption bands associated with photoinduced rearrangement to benzoyl chloride were observed accompanying the weak bands due to the CO photolysis product. However, in the reactive O 2 matrix, isomerization was observed and there was no evidence of benzoyl chloride formation. A kinetic analysis revealed that rearrangement was a minor process under the present excitation energy. The TD-B3LYP calculations show that as the excitation energy increases the predissociation channel will open and the repulsive 1 (, * C-Cl ) and 1 (n, * C-Cl ) states are directly achievable by the 185 nm excitation. Photoinduced rearrangement will be caused by the reaction of thus dissociated cage pairs.
