Abstract
NO dispersed VUV-fluorescence excitation (λfl = 134-152nm) was measured as a function of the exciting-photon energy between 16.9 and 19.6eV using monochromatized synchrotron radiation with a bandwidth of 6.5meV. A two-dimensional fluorescence excitation spectrum was obtained, where the intensity is plotted as a function of both fluorescence wavelength and exciting-photon energy. Fluorescence from NO+ A1Π (v = 0,1,2) vibronic levels and fluorescence from excited dissociation fragments NI (3s 2PJ) was observed simultaneously. Fragment state selective predissociation and autoionization of the NO: (c 3Π)3pπ (v = 0) and (c 3Π)3pσ (v = 0) Rydberg states were observed simultaneously.
