[(? 2-C2H4)Os(CO)4] as a vibrational model for type I? ethene chemisorbed as a metallacyclopropane on metal surfaces
Autor: Christopher E. Anson, Norman Sheppard, Bruce R. Bender, Donald B. Powell, Jack R. Norton
Publikováno v: Journal of the Chemical Society, Faraday Transactions. 90:1449
A comprehensive vibrational assignment of the hydrocarbon features in the infrared and Raman spectra of (η2-C2H4)Os(CO)4 has been achieved with the help of data from the (13C2H4) and (C2D4) isotopologues. Close analogies with the vibrational spectra
