The adsorption of multiple nitric oxide molecules on rhodium cluster cations, Rhn+ (n = 6 and 7), was studied by infrared multiple photon dissociation spectroscopy in combination with density functional theory calculations. For n = 6, the first NO molecule adsorbs molecularly on an on-top site of octahedral Rh6+. The second NO molecule adsorbs either molecularly on another on-top site or dissociates into N and O atoms, with ca. 1:0.4 propensity. The adsorption of a third NO molecule results in the formation of Rh6+(NO)3 with two molecularly adsorbed NO on on-top sites and one dissociatively adsorbed NO. For n = 7, the first NO molecule adsorbs molecularly either on an on-top site or on a bridge site of Rh7+, followed by partial dissociation into an O atom on a bridge site and the N atom on a hollow site. When a second NO molecule adsorbs on Rh7+(NO), a Rh7+(NO)2 structure is formed with one NO molecule adsorbed on an on-top site and the other NO molecule adsorbed dissociatively. The adsorption of a third ...
