Abstract
The rotational analysis of bands of P16O and P18O molecules has been carried out by emission experiments. These bands, all perturbed, correspond to transitions from A2Σ+, F2Σ+, G2Σ+, H2Σ+ and I2Σ+ to B2Σ+, A2Σ+ and X2Π states in the respective regions 3850–5300, 6500–7000, and 1800–2000 Å. The results of first- and second-order deperturbations for the observed interactions give the values of the constants of the F, G, H, and I states with a better accuracy than that obtained previously by Verma et al. Particularly, they infirm the hypothesis of a predissociation of some vibrational levels by the repulsive A′2Σ+ state and permit the assignment of a new quantum specification to the H2Σ+ state. The electronic structure and the order in energy of the Rydberg states considered are then consistent to those which have been proposed by Ackermann et al.
