✦ Synopsis

In the electronic emission spectrum of the isotopic carbon monoxide ion 13 C 16 O + molecule, seven bands of the comet-tail (A 2 i -X 2 + ) system have been recorded and analyzed. The spin splitting in most observed lines of the bands 1-0, 2-0, 3-0, 4-0, 5-0, 2-1, and 7-1 comprising over 1900 lines has been recorded under high resolution by using conventional spectroscopy. The rotational analysis of bands has been performed by nonlinear least-squares procedures and by means of effective Hamiltonians of Brown et al., the rovibronic structure parameters have been obtained. As a result of multistaged and merged analysis of the currently obtained bands of the A-X system and of the bands of the B-X system obtained earlier the state of information about the energy structure has been significantly enlarged for the A state and enlarged and improved for the X state. Also RKR potential curves have been calculated for both states and Franck-Condon factors as well as r -centroids of the comet-tail system of 13 C 16 O + .

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 Ã 2 -X 2 + transition. Rotational analysis yields the molecular constants of the vibronic levels, (1,0,0) and (1,0,1), in the Ã 2 state.
