Abstract
The Pd+CO reaction has been reinvestigated using deposition of ground state reagents in solid argon and neon and the formation of PdnCO (n=2-5) is evidenced by strong absorption in the range 2015-1650 cm−1 . Various isotopic data ( 12C/13C,16O /18O, natural isotopes for the palladium) and number of two quantum transitions have been measured in the near- and far-infrared regions. In argon, selective irradiation in visible leads to conversion between two Pd2CO isomers distinguished by the stretching frequency of the diatomic CO: bridged T-shaped (νCO= 1856 cm−1 ) and side on (νCO= 2015 cm−1 ). DFT calculations of the geometrical and electronic properties of PdnCO complexes are also presented and compared to the experimental values.
