  • Abstract In the fluorescence excitation spectra, fluorescence cross sections can be measured by the normalization of absorption cross section of A(0) or D(0) states. In the presence of foreign gases, the self-quenching rate constants, the half-quenching pressures and the quenching rate constants of D(0) and D(1) states are measured and the results are compared with the previous works. In the additional of foreign gases, the enhancement of global fluorescence of the strong predissociation states of C(1) and B(9) is due to the collision-induced transition. In the case of N2, the enhancement of fluorescence of ╬│band is owing to the resonance transfer. Finally, the well depth of the van der Walls molecules which are formed by the excited state of NO with quenching gas can be derived from the measured quenching cross sections.
