We report high-resolution fluorescence studies of the rotational structure of the HgAr A 30+–X 10+ (1≤v′≤6, v″=0) vibrational bands which occur near to the Hg 6s2 1S0–6s6p 3P1 (254 nm) atomic resonance. The molecules were formed in a supersonic jet expansion and were excited by UV radiation produced by intracavity second-harmonic generation in a cw dye laser. The intensity profile of each band was reproduced by a theoretical model. Least-squares fits to the experimental spectra yielded accurate values for the band origins, rotational constants, and isotope shifts. This information was used in a Rydberg–Klein–Rees evaluation of the A 30+ potential, which was found to differ slightly, but significantly, from a Morse function in the region probed by this experiment. © 1996 American Institute of Physics.
