Transition Energies and Line Oscillator Strengths of the C2Π(0)-X2Π(0–6) Absorption Bands of Nitric Oxide. A Theoretical Study

Theoretical absorption oscillator strengths and wavelengths for rotational transitions of the C2Π(v′ = 0)-X2Π(v″) bands with v″ = 0–6 of nitric oxide are reported. The Molecular Quantum Defect Orbital method has been used in the calculations and the known interaction between the C2Π(v = 0) Rydberg a...

More Information
Summary:Theoretical absorption oscillator strengths and wavelengths for rotational transitions of the C2Π(v′ = 0)-X2Π(v″) bands with v″ = 0–6 of nitric oxide are reported. The Molecular Quantum Defect Orbital method has been used in the calculations and the known interaction between the C2Π(v = 0) Rydberg and the B2Π (v = 7) valence states has been dealt with through an appropriate rovibronic energy matrix. We hope that the reported data may be useful in the analysis of the observed ultraviolet nightglow emission from nitric oxide in the upper atmospheres of Earth, Venus, and Mars.
