Abstract: | We have generated MgNC in supersonic free jet expansions and measured the laser-induced fluorescence excitation spectra of the C-N stretching vibronic bands of the Ã2Π-X?2Σ+ transition. Rotational analysis yields the molecular constants of the vibronic levels, (1,0,0) and (1,0,1), in the Ã2Π state. We cannot find any anomalies in the constants of these vibronic levels, while they are predicted to lie above the barrier of the isomerization reaction pathway, MgNC↔MgCN, on the Ã2Π state. On the basis of the molecular constants obtained, we discuss the fine structures of both the ground X?2Σ+ and excited Ã2Π states. |
