... The increase in electron density at the nickel from PR3 σ-donation is dispersed through the M-L π system via π-backbonding. Much of the electron density is passed onto the CO π* and is reflected in decreased v(CO) stretching frequencies which corresponds to weaker CO bonds. CO stretching frequencies ...
