ROTATIONAL ANALYSIS OF THE H1(U)[-A0(G)(+ -) (1,0) BANDS OF (HG-202)(2)/

Isotopically pure Hg-302 vapor, contained in a quartz cell, was irradi ated with the 2572.5-Angstrom output from a frequency-doubled Ar+ lase r, which produced Hg-2 A0(g)(+/-) excimer molecules by photoassociatio n followed by collisional relaxation. Simultaneously applied probe rad iation from a ring laser, scanned over the range 4150-4400 Angstrom, g ave rise to the H1(u) <-- A0(g)(+/-) v' = 1 <-- v '' = 0 excitation ba nds consisting of about 490 rotational components. The bands were subj ected to a rotational analysis which yielded spectroscopic constants t hat are compared with some previous data. (C) 1997 Academic Press, Inc .
