Rotational analysis of the bands of the B-A transition in isotopic CO/+/ molecules

Abstract

The violet-degraded B-A bands of 12C16O +, 12C18O +, and 13C18O + molecules emitted from a hollow-cathode discharge tube have been photographed at high resolution in the region between 4250 and 3500 A. Rotational analysis of the (0, 1) band of 12C18O+, the (0, 0), (1, 0) bands of 12C18O+, and (1, 0), (0, 0), and (0, 1) bands of 13C18O+ has been performed and molecular constants for their respective initial and final states B 2 + and A 2flj have been determined.
