s-Tetrazine argon complexes T−Arn (n = 1, 2) are formed in a supersonic expansion of argon seeded with s-tetrazine. The expansion was conducted through a nozzle of 50 or 100 μm with an argon stagnation pressure between 1 and 1.5 bar. From spectrally resolved measurements it is clear that vibrational redistribution processes as well as vibrational predissociation processes take place after SVL excitation within the complex.From rise and decay time experiments it can be concluded, that after excitation of the 6a1 complex level, the above mentioned processes are consecutive and not parallel. It appears that the out of plane mode 16a couples with the Van der Waals stretching mode. The predissociation rate of the 16a2 complex is observed to be 2.3 × 109 s−1.

Single Transition

The S1 energy levels of isotopically mixed benzene dimers are studied in a supersonic expansion. In the benzene dimer the O-O transition which is forbidden in the bare molecule is weakly allowed. The spectra show a small splitting for the homodimer and a single transition for the heterodimer, and an additional red shift of the homo dimer transition.
