Abstract
We studied The magnetic field effects under the ``direct” rf discharge excitation of the B state levels, and under The direct observation of the LIF signal for the 0-9 transition excitation. It has been found that the emission of the 0-9 transition induced by the rf discharge and by the laser irradiation in the presence of the rf discharges have been quenched by a field with the same profile on the field strength. The observed data can not be explained by the mechanisms discussed in the literature. Therefore, we have proposed two schemes - the 3-resonance levels scheme and two 2-levels one, which can be used for analysis of the; magnetic field effects in the NO fluorescence. According to the general statements the two 2-levels system is most real, thin the 3-levels one in case of the diatomic molecule. Detailed analysis of these mechanisms shows that the total set of the observed data can be explained by these schemes
