Abstract Using time-resolved laser-induced fluorescence(L1F) spectroscopy, the fluorescence quantum beat decay was observed in C ( 1B2 ) ← X(1A1) transition of SO2 molecule. The experimental results show that only the v3 mode and its combination band v1 + v2 + v3 excitation exist the beat decay. Analyzing the result, we attribute the quantum beat states to the coupling of the v3 vibration mode of C state with the high vibrational levels of the electronic ground state.
