Optical-optical double resonance multiphoton ionization(OODR-MPI)spectroscopy is a rapidly developing, versatile technique which should find wide applications in both molecular spectroscopy and molecular dynamics. In an OODR-MPI study of CO, we irradiate the static sample cell by 2 pulsed dye laser beams. The first UV laser light (“pump beam”) resonantly pumps ground state CO to A~1∏ state via a 2-photon process. Then a second visible laser light (“probe beam”) excites CO A~1∏ to B~1∑~+. The excited B~1∑~. The excited B~1∑~+ molecule further undergoes ionization by absorbing one more UV photon, so the whole process follows a 2+1+1 photon scheme....
