Abstract
In the present study, the magnetic field influence on the NO fluorescence induced by the B2(Pi) ((upsilon) equals 0) yields X 2(Pi) ((upsilon) equals 9) transition was investigated upon the direct population of the B2(Pi) ((upsilon) equals 0) level by the processes: NO[X2(Pi) ((upsilon) equals 0)] + N2(A3(Sigma) +u) yields NO]B2(Pi) ((upsilon) equals n)] + N2; NO[B2(Pi) ((upsilon) equals n)] + M yields NO[B2(Pi) ((upsilon) equals 0)] + M; and by the aforementioned processes together with the processes: NO[B2(Pi) ((upsilon) equals 0)] yields X2$ (Pi ((upsilon) equals 9) + hvfl; X2(Pi) ((upsilon) equals 9) + hvexc yields NO[B2(Pi) ((upsilon) equals 0)]. Data observed in the present study and published in literature were explained by the model including 'gateway' mechanism, developed by Ottinger and Vilesov, in combination with the magnetic field coupling mechanism of the rovibronic levels belonging to the B2(Pi) ((upsilon) equals 0) and X2(Pi) ((upsilon) equals n) states. In a frames of this model, it was assumed that the fast collision-induced transitions are realized between the rovibronic levels of the B2(Pi) ((upsilon) equals 0) state.
