| Abstract
| - The reactions of two group 10 metal atoms, nickel and platinum, with oxygen molecules at low temperaturein solid argon have been reinvestigated. New information has been gathered on the interactions betweentransition metals and oxygen, more precisely, on platinum and nickel superoxides and their insertion products.For Pt(O2) the low-frequency metal−ligand ν2 and ν3 fundamentals have been observed and derived harmonicpotential constants are compared to those of Ni(O2). Interest will then be taken in the dioxide insertion products,their differences in bonding as well as their production mechanisms. The positions of all three fundamentalsfor OPtO and of the two IR-active vibrations for ONiO have been experimentally determined and are comparedto recent ab initio predictions.
