The Electronic Spectrum of AuO:  A Combined Theoretical and Experimental Study

Abstract

The near-infrared electronic spectrum of AuO has been re-examined in light of the new microwave data on\nthe <i>v</i> = 0 and <i>v</i> = 1 vibrations of the <i>X</i>Π_3/2 state of AuO. The two observed bands in the spectrum, with\nred-degraded bandheads located at 10726 and 10665 cm^-1, have been reanalyzed. New theoretical work on\nAuO clarifies the electronic structure, and the bands in the infrared are now assigned as the (0,1) and (1,2)\nbands of the <i>a</i>⁴Σ^-_3/2 − <i>X</i>²Π_3/2 transition, respectively.
