| 摘 要： | A rotational excitation spectrum of SO2 ^-A^1A2(511)←^-X^1A1(000)] at about 33331cm^-1 in free jets was observed by using the forward degenerate four-wave mixing (DFWM).Twelve lines of the G band and 11 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.
