✦ Synopsis

We report the first successful demonstration of a LIF study performed on small molecular ions in a jet expansion produced by resonantly enhanced multiphoton ionization. The study involves the 2 + 1 multiphoton ionization via the B 'X + state ofjet-cooled CO molecules. Sufftcient downstream densities are achieved to perform rotationally resolved LIF spectroscopy on both the X 'II +A *E transition of CO+ and the triplet third positive group of CO. The consequences of experimental conditions on the branching ratio of the products are discussed.
