Abstract
The vibronic intensities for band systems of NO corresponding to transitions with origin in both the X(2)Pi ground and the 3ssigma(A(2)Sigma(+)) Rydberg states, and ending in the nppi Rydberg series with n = 3-5, have been determined. The description of the Rydberg states has been made with the molecular quantum defect orbital methodology. The Rydberg-valence interaction of the (2)Pi symmetry states involved in the studied transitions has been analyzed through a vibronic matrix. The present results have been compared with experimental and theoretical data available in the literature. Additionally, predictions for a number of unknown intensities have been made, which may be useful for the interpretation of the spectrum of NO.
