AbstractThe emission spectrum of CrO has been investigated by Fourier transform spectroscopy in the near infrared. New weak electronic bands have been found in the 6000- to 10 000-cm -1 region, the strongest of which, near 8000 cm -1, is shown to be the (0,0) band of a 5Σ- 5Π transition where the 5Π lower state is the ground state. Fifty branches have been assigned in this band, which have permitted the first detailed characterizations of quintet electronic states in the gas phase. Accurate values have now been obtained for the spin-orbit coupling and Λ-doubling intervals in the ground state (which could only be estimated in the previous laser-induced fluorescence work in the visible region by Hocking et al. [Canad. J. Phys.58, 516-533 (1980)]). The relative branch intensities are not consistent with those calculated for a pure 5Σ- 5Π(a) transition, and indicate considerable spin-orbit contamination such that there are interference effects between two or more competing transition moments. It is not known whether the 5Σ excited state is 5Σ + or 5Σ -. © 1984.
