Tunable and coherent vacuum ultraviolet radiation is now available over broad regions from 200 to {similar to}60 nm. It is generated by third harmonic and four-wave frequency mixing in gases and metal vapors, and is of sufficient intensity for absorption and fluorescence spectroscopy. We have recently applied these sources to studies of Xe{sub 2}, Kr{sub 2}, and Ar{sub 2} produced by supersonic jet expansion. Vibronic spectra of Xe{sub 2} and rovibronic spectra of Kr{sub 2} and Ar{sub 2} arising from transitions between the ground and three lowest (stable) excited states have been recorded at resolving powers of 1--5{times}10{sup 5}. Spectroscopic constants have been derived, potential energy curves computed, and radiative lifetimes measured and compared with theory.
