Recent high-resolution measurements of the - bands in PN have provided additional information about the perturbations of the low-lying vibrational levels resulting from interactions with nearby valence states. The primary interaction arises from the excited state. Multireference configuration-interaction calculations were performed on the and states of PN in order to gain some insight into the probable accuracy of theoretically predicted spectroscopic constants for the state, including , and .
