The near-infrared electronic spectrum of AuO
1 has been re-examined in light of the new microwave data onthe
v = 0 and
v = 1 vibrations of the
X23/2 state of AuO. The two observed bands in the spectrum, withred-degraded bandheads located at 10726 and 10665 cm
-1, have been reanalyzed. New theoretical work onAuO clarifies the electronic structure, and the bands in the infrared are now assigned as the (0,1) and (1,2)bands of the
a4-3/2 -
X23/2 transition, respectively.
