Optogalvanic spectrum of CO. II. The rotational structure of the L 1Π state
Abstract
The Q branch and P, R branches of the 4pπL 1Π-3sσB 1Σ+ transition of CO have been newly observed by high resolution and low resolution optogalvanic spectroscopy, respectively. The value of the Λ-type doubling constant in the L 1Π state has been determined as q=0.0213±0.0012 cm-1. An accidental perturbation was discovered in the Π- component of the L 1Π state. The Angstrom (0-3) and (0-4) bands were also observed.
