Predissociation of the N+2C 2?+u(v') vibrational levels with v' ? 3 was observed via dispersed C 2?+u? X 2?+gfluorescence in the spectral range of 165-208 nm after resonant 1s?1?*(vr) excitation of N2and its subsequent autoionization into the N+2C state. This range is dominated by lines in atomic nitrogen, by overlapped C 2?+u(v') ? X 2?+g(v'') vibrational band sequences with ?v= const and broad unresolved band systems (D, (2))2?g(v') ? A2?u(v'') in the N+2molecular ion. With very high fluorescence resolution of about 0.1 nm FWHM individual C 2?+u(v') ? X 2?+g(v'') vibrational bands have been resolved. Calculation of the observed fluorescence spectra by taking into account predissociation and molecular rotation describes well the shape of both individual vibrational bands C 2?+u(v') ? X 2?+g(v'') and the whole band system. |
