Abstract

A laser induced fluorescence excitation spectrum has been obtained for sym-triazine seeded in a free jet expansion in He. Under these conditions, the translational, rotational, and (probably) vibrational temperature of the sym-triazine is found to be 1°K. This low temperature yields a greatly simplified vibronic spectrum for the Ã¹E″↔X̃ ¹A′₁ transition, with implications for vibrational assignments and the interpretation of the Jahn-Teller and pseudo-Jahn-Teller effect in the Ã¹E″ state. Completely resolved R and P rotational structure has been observed for selected vibronic transitions. Lifetime and collisional quenching cross sections have also been obtained for selected vibronic levels of the Ã¹E″ state.
