Absorption spectra of ground-state and low-lying electronic states of copper nitrosyl: A rare gas matrix isolation study

Reinvestigation of the vibrational and electronic spectra of the Cu atoms with NO during condensation in solid argon, and binary argon/neon mixtures is carried out. The molecule is bent in all electronic states with Cu-N-O bond angles varying slightly around 130(plusmn)10 degree, but the Cu-N bond force constants are substantially different, denoting larger differences in bond lengths.
