Comparing spectroscopic and electrochemical properties of complexes of type Cp'M(η3-C3H5)(CO)2 (Cp' = Cp, Ind, Flu): A complementary experimental and DFT study

How does η5-C5-ring substitution influence [Cp'M(η3-C3H5)(CO)2] complex properties according to 95Mo NMR, IR, PES, and oxidation potentials? What can be learnt from DFT?227
