✦ Synopsis

Isotopically pure 2°2Hg vapor, contained in a quartz cell, was irradiated with the 2572•5 ,~ output from a frequency-doubled Ar + laser, which produced Hg 2 A0g ~ excimer molecules by photoassociation followed by collisional relaxation• Simultaneously applied probe radiation from a ring laser, scanned over the range 4150-4650 A, gave rise to the H1 u ~ A0g and H1 u *--A0~-excitation spectra consisting of several hundred rotational components. Two previously unobserved rovibronic bands (one in each spectrum) were subjected to a rotational analysis which yielded spectroscopic constants that are compared with some previously reported values•
