Theoretical study of the rotational structure of the γ(0, 0) band of NO. Molecular quantum defect orbital (MQDO) calculations of Einstein absorption coefficients and line-integrated rotational cross sections

In the present work, a fairly large number of rotational transition probabilities, in the form of both Einstein absorption coefficients and line-integrated photoabsorption cross sections, have been theoretically determined for the rovibrational structure of the γ(0, 0) band of NO, within the A 2Σ ← X 2Π electronic transition. A temperature of 295 K has been considered. The calculations have been performed with the molecular quantum defect orbital (MQDO) methodology, which has recently proved to be a very adequate tool for this type of studies, by yielding quantitative values for the δ(0, 0) band of the same molecule.
