Abstract
Expressions are developed for the magnetic dipole line strengths of rotational transitions in theA-band (0–0 band) of the atmospheric oxygenb 1Σ + g −X 3Σ − g ) system. The line strengths so derived incorporate effects of spin-uncoupling and orbit-rotation interaction besides, of course, spin-orbit perturbation and are absolute in the sense that the dominant transition moment and intensity parameter which enter the formulae are explicitly expressed in terms of the mutual perturbations characterizing theb andX states. SinceS-branch transitions (necessarily) of electric quadrupole character, have also been detected in theA-band (Brault [11]), we have included a general discussion of branch line strengths for the electric quadrupole intercombination transition1Σ+−2Σ−.
