A PRDDO-GVB theoretical SCF-MO study of the torsion of ethylene in its ground state

A detailed study for different torsion angles of the HF-PRDDO and GVB-PRDDO wavefunctions of ethylene is made, including the correlation energy obtained through the GVB formalism, non-analiticities in certain HF-predicted curves, valency and degree of bonding, and the ability of the methods to descr...
