Dissociation dynamics of methylazide on the first excited singlet surface

The photolysis of methylazide around 313 nm is studied experimentally by laser Raman spectroscopy. The emission spectrum with a resolution of 50 cm−1 is reported. Based on our experiments, the photodissociation of methylazide on its first excited singlet surface is proposed to be a concerted N2 elimination and 1,2-H shift process.
