Quantum mechanical treatment of molecules. Part 4.—RKR Franck-Condon factors for the γ and β band systems of the NO molecule

The Franck-Condon factors and the r-centroids based on the vibrational wave functions appropriate to the Rydberg-Klein-Rees (RKR) potential energy curves, have been computed for the γ and β band systems of the NO molecule. These have been compared with the RKR and the Morse Franck-Condon factors reported by the previous workers. The variation of the electronic transition moment with the internuclear distance has been obtained for the γ system of NO by a new technique as well as by the r-centroid method and the “smoothed” relative band strengths for this system have been calculated.
