Abstract A rotational excitation spectrum of SO2 [ A 1A2 (511) ← X1A1 (000)] at about 33331 cm-1 in free jets was observed by using the forward degenerate four wave mixing (DFWM). Twelve lines of the G band and eleven ones of the E band were marked based on the rotational constants according to Hamada's result [Can. J. Phys. 53 (1975) 2555]. The relation between the DFWM signal intensity and the pressure of the buffer gas in free-jets was experimentally investigated.
