What is Consecutive Processes in the Photolysis of Dimethyl-s-tetrazine Molecules in the Vapor Phase about?

Experimental studies of the wriatlon of the fluorescence yield and photochemical product yield are presented for &methyl-s-tetrazine (DMT) ac 0.6 TOIT and 300 K. Results arc also reported for the variation of these yields upon adding argon buffer gas. The fluorescence yield decreases with increasing exntition eneq) (0 to 4200 cm-' vibrational energy excess UI the fist evclted s&et state) but the decrease IS insufficient to account for the corresponding increase in product yield. Added pas (600 Torr argon) quenches the photochemistry but not the fluorescence. The results unply that the photorhssoaahon mvolves a bottleneck (B) in the non-radiative smglet decay. The molecules in B can be rehxcd by coll%ion~. relax to photostable DMT molecules wthout collisions, or undergo photodrssociatlon.
