✦ Synopsis

We report on the two-photon visible excitation spectra of potassium molecules in a supersonic beam. A dye laser excites K, to different (7s 'X,, 9s 'Es, Sd 'As) Rydberg states. Two-photon transitions are detected by monitoring the resulting (third-photon) ionization. We have made detailed studies, including rotational assignment of 92 such transitions, 'As( v*, J*) + X 'Z,( v" = 0, J"), where the B'II u state forms the intermediate enhancing state.
