Spectroscopy of AuO: Identification of the [10.7] Pi(3/2) to X-2 Pi(3/2) transition
The near-infrared electronic spectrum of AuO has been recorded in emission using the Fourier transform spectrometer associated with the National Solar Observatory at Kitt Peak, AZ. The gas-phase AuO molecules were produced in a neon-based electric discharge using a gold-lined hollow cathode with a trace amount of oxygen. Two bands observed in the spectrum, with red-degraded bandheads located at 10665 and 10726 cm(-1), are assigned as the (1,1) and (0,0) bands of the Pi(3/2) to X(2)Pi(3/2) transition, respectively. Results of the analysis are presented. This work and the accompanying paper(1) on the photoelectron spectrum of AuO and AuO- represent the first spectral observations of gas-phase AuO.
