Abstract	The pressure saturation effect on the phosphorescence decay rates of the 3B1 State of SO2 has been reinvestigated by the laser induced phosphorescence method in pure SO2. We have attempted to fit the pressure dependence of the phosphorescence decay rates using the radiationless transition model by introducing different coupling constants for each vibrational level ofthe 3B1 state. The experimental decay rates can be fitted well, when the coupling constants for the (0,0,0), (0,1,0) and (0,2,0) levels of the 3B1 state are 7.2 × 10-4, 2.2 × 10-3 and 5.9 × 10-3 cm-1, respectively.
