Abstract

Transitions between the A¹p{cyrillic} and B¹∑⁺ states of CO are studied by first exciting A¹p{cyrillic} by a two-photon excitation. A second laser scans the various vibrational transitions between the A ¹p{cyrillic} and B ¹∑⁺ states. Signals arising from the subsequent ionization of the B ¹∑⁺ population provide rovibrational assignments for the two excited states. Additionally, a two-photon rate of 5 × 10^-11 I² cm⁴ W^-2 5^-1 and a photoionization cross section of 1.4 × 10^-20 cm² were measured for this process.
