Absorption oscillator strengths for vibronic transitions of nppi Rydberg series in NO.
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.
