The pressure dependence of the recombination rate constants for Mo (CO),(n= 3, 4, and 5) with CO has been studied by time-resolved infrared laser absorption spectroscopy. These data, in conjunction with an RRKM model for unimolecular decay of the activated molecules [Mo (CO),]*,[Mo (CO),]*, and [Mo (CO),]*, have allowed the determination of the bond dissociation energies for several of the Mo-C bonds in Mo (CO),. The first Mo-C bond ...
