• The $C^2\Pi$-$X^2\Pi$(0, 0) band of AgO has been reinvestigated by laser induced fluorescence spectroscopy with a spectral resolution of $\sim$0.02 cm$^{-1}$. The AgO molecules are produced by discharging a gas mixture of O$_2$/Ar with silver needle electrodes in a supersonic jet expansion. By employing a home-made narrowband single longitude mode optical parametric oscillator (SLM-OPO) as the laser source, high-resolution spectra of the $C^2\Pi$-$X^2\Pi$(0, 0) band have been recorded for both $^{107}$Ag$^{16}$O and $^{109}$Ag$^{16}$O isotopologues. The spectroscopic constants of the $C^2\Pi$ state are consequently determined, with the $^{109}$Ag$^{16}$O one being reported for the first time. The nature of the spin-orbit coupling effect in the $C^2\Pi$ state is proposed to be due to state mixing with the nearby repulsive $^{4}\Sigma^{-}$ and $^{4}\Pi$ states.

Abstract: The $C^2\Pi$-$X^2\Pi$(0, 0) band of AgO has been reinvestigated by laser induced fluorescence spectroscopy with a spectral resolution of $\sim$0.02 cm$^{-1}$. The AgO molecules are produced by discharging a gas mixture of O$_2$/Ar with silver needle electrodes in a supersonic jet expansion. By employing a home-made narrowband single longitude mode optical parametric oscillator (SLM-OPO) as the laser source, high-resolution spectra of the $C^2\Pi$-$X^2\Pi$(0, 0) band have been recorded for both $^{107}$Ag$^{16}$O and $^{109}$Ag$^{16}$O isotopologues. The spectroscopic constants of the $C^2\Pi$ state are consequently determined, with the $^{109}$Ag$^{16}$O one being reported for the first time. The nature of the spin-orbit coupling effect in the $C^2\Pi$ state is proposed to be due to state mixing with the nearby repulsive $^{4}\Sigma^{-}$ and $^{4}\Pi$ states.
