Abstract : The mass spectrum and the optical spectrum were studied as functions of time for the process and products of flashinitiated decomposition of benzenediazonium-3-carboxylate. The products of decomposition include a transient parent C6H4 species of mass 76. The fragmentation pattern and its time dependence show that the mass 76 species is different from either of those obtained from the ortho or para isomers of the precursor. Comparison of the fragmentation pattern with model compounds suggests that 1,3-dehydrobenzene probably in a singlet state, is the most likely assignment of the species. Two structural representations are proposed. (Author)
