In this paper we report an extension of our earlier study on the structure of Alfacetone)2 (+) Collision-induced dissociation (CID) on MfacetoneXacetone-d6)(+) for M = Al, Fe, Co, and Cu yields primarily, if not exclusively, nearly equal amounts of acetone and acetone-d6. Likewise, infrared multiphoton dissociation (IRMPD) at 10.6 μm yields, exclusively, nearly equal losses of the labeled and unlabeled acetones. These results suggest that the two acetone ligands bind in an equivalent fashion. Sc(+) was also studied, which proved to be the most interesting. Sc(+) reacts with acetone to form primarily ScO(+), which undergoes higher order reactions leading to several products including ScO(acetone)2 (+). IRMPD on this ion produces ScO(acetone-d6)(CD2CO)(+), while its perdeuterated analog also produces ScO(acetone-d6)(+) in addition to ScO(acetone-d6(CD2CO)(+). The IRMPD results are supplemented by studying the primary and higher order reactions of Sc(+) with acetone, as well as the CID of ScO(acetone)2 (+). Finally, a qualitative assessment of the infrared photodissociation cross sections is given. It is found that the relative photodissociation cross sections follow the orders Co(acetone-d6)2 (+) > Co(acetone)(acetone-d6) > Co(acetone)2 (+) and Co(acetone-d6)(+) > Co(acetone)(+).
