Abstract
All perturbations observed by Lagerqvist (Thesis, University of Stockholm, 1948) in the A1Π-X1Σ+ transition have been assigned to a3Π2, a3Π1, and X1Σ+ states. Vibrational and rotational constants of the a3Π state as well as electronic parameters for A ∼ X, A ∼ a, and a ∼ X interactions have been determined. Reciprocal centimeters Te ωe ωexe Be αe re (Å) a3Π 8574 1132 8.4 1.3675 −0.0168 1.4623 The combination of ab initio calculations with experimental data was found essential to carry out the deperturbation of the BeO A1Π state and show a very coherent picture of the A1Π perturbations.
