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 and
