摘　　要：The quenching effects of N2, NO2 and H2O on the laser-induced fluorescence of I2in a wide pressure range are reported. The quenching rates of N2, NO2 and H2O are 6. 57 ×103 Pa-1, 2. 58 × 10-2 Pa-1 and 1. 50 × 10-2 Pa-l, respectively. The results imply thatdipole-induced dipole interaction plays an important role in the quenching process, and thestatic quenching of NO2 on I2 fluorescence could be attributed to the metastable complexformation of I2 andThe quenching effects of N_2, NO_2 and H_2O on the laser-induced fluorescence of I_2in a wide pressure range are reported. The quenching rates of N_2, NO_2 and H_2O are 6. 57 ×103~ Pa-1, 2. 58 × 10-2 Pa-1 and 1. 50 × 10-2 Pa-l, respectively. The results imply thatdipole-induced dipole interaction plays an important role in the quenching process, and thestatic quenching of NO2 on I2 fluorescence could be attributed to the metastable complexformation of I2 and NO2
