Carbon Monoxide Binds Strongly To The Fe2

Carbon monoxide binds strongly to the Fe2+ ion of the haem group of the protein myoglobin. Estimate the vibrational frequency of CO bound to myoglobin by using the data in Problem 9.2 and by making the following assumptions: the atom that binds to the haem group is immobilized, the protein is infinitely more massive than either the C or °atom, the C atom binds to the Fe2+ ion, and binding of CO to the protein does not alter the force constant of the c=o bond.
