DFT (density-functional theory) calculations were performed to investigate the thermodynamics of formation of Olefin Separated Ion Pairs (OSIP) Cp2MtCH~/C2H4/Cl2AI[O(A1Me3)AlHMe]; (Cp = q5-C5H5, Mt = Ti, Zr, Me = CH3) from ethylene and Cp2MtMe \* C12AI[O(AlMe3)A1HMe]2, a model of adduct produced by
