AbstractThe absorption spectrum of the (2, 0) and (2, 1) bands of the B 2Σ +-X 2Σ + transition of YO between 442 and 478 nm were recorded using laser vaporization/reaction with free-jet expansion and cavity ring down laser absorption spectroscopy. Local rotational perturbations have been found for both spin components of the v = 2 level of the B 2Σ + state. The observed perturbations could be ascribed to a degenerate perturbing state interacting with the B 2Σ + state. Least-squares fit of the observed upper state term values yielded molecular constants for the v = 2 level of the B 2Σ + state and the perturbing 2∏ state. Earlier ab initio calculations [J. Chem. Phys. 89 (1988) 2160] indicated that the C 2∏ state is nearby, it is plausible that the C 2∏ state is the perturbing state. © 2004 Elsevier Inc. All rights reserved.
