Abstract
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.
