Abstract. Negative ions of copper clusters reacted with nitric oxide molecules are studied by mass-selected photoelectron spectroscopy. The series of the reacted cluster ions, Cu n N-, Cu n NO-, and Cu n NO2 - are observed in the mass spectrum. Photoelectron spectra are obtained at 3.49 eV photon energy for Cu n N- (n=2 and 3) and Cu n NO2 - (n=1 and 2). The photoelectron spectrum of Cu2N- contains a band structure analogous to that of Cu- or Cu2 -. From the expansion gas pressure dependence of the band peak intensity in the spectrum, it is concluded that Cu2N- has at least two isomers in the beam. One of the isomers is expected to have a structure in which the central ion is Cu- or Cu2 - and the residual atom(s) are weakly bound to the ion. For Cu n NO- (n=1-3), we detected no electron signals with the detachment photon energy of 3.49 eV. The possible structure of CuNO- is discussed in the light of the present results and also on the basis of the recent results of the study of CuO2 - by Wang and coworkers.
