英文摘要	The electronic spectrum of the copper monoxide molecule (CuO) was investigated in the range of 430-550 nm using laser induced fluorescence spectroscopy and single vibronic level emission spectra. The CuO molecule was produced by a supersonic jet-cooled discharge assisted laser ablation of Cu target. Twenty two vibronic bands were observed and assigned to the electronic transition progressions from the ground state X-2 Pi(i) to excited states C-2 Pi(3/2), C-2 Pi(1/2), D-2 Delta(5/2), E-2 Delta(5/2), F-2 Pi(3/2), G(2)Sigma, H-2 Pi(3/2), and I-2 Pi(3/2), of which ten bands were recorded firstly. The molecular constants of the excited electronic states for (CuO)-Cu-63 and (CuO)-Cu-65 isotopologues were obtained by a rotational analysis of the spectra. Cascading processes in the electronic excited states were found combining the time-resolved single vibronic level emission spectroscopy. The time-dependent radiative decay curves corresponding to different decay processes were recorded and analyzed. (C) 2019 Elsevier Inc. All rights reserved.
