摘要：

Closed form expressions are developed for the intensity factors of the 23 branches resulting from a 3Σ±(int)±3Σ±(int) electric quadrupole transition in a diatomic molecule. The rigorous intermediate coupling treatment which includes centrifugal distortion effects results in the occurrence of the U-form and M-form branches which are forbidden in the limit of Hund's case (b) in both the 3Σ states. The branch intensity factors are used to recalculated the absorption intensities of rovibrational transitions in the quadrupole fundamental band of O2. It is shown that depature from the strict case (b) limit moderately affects the intensities of some of the low J transitions. © 1990.
