摘要：

The near-infrared electronic emission spectrum of ScN has been observed in the 1.6-1.8-mu-m spectral region using a Fourier transform spectrometer. The three bands with origins at 5820.0944(5), 6051.2858(20), and 6266.1290(13) cm-1 have been assigned as the 0-0, 1-1, and 2-2 bands of the A (1)SIGMA+ X (1)SIGMA+ electronic transition. The principal equilibrium molecular constants for the ground state obtained from a fit of the observed lines are B(e)" = 0.554 609(17) cm-1, r(e)" = 1.687 23 (3) angstrom and the corresponding values for the excited state are B(e)' = 0.549 277 (17) cm-1, r(e)' = 1.695 40(3) angstrom. Although ScN is a well-known refractory solid, our work is the first observation of the gas-phase ScN molecule.
