Abstract
Ab initio calculations of the molecular geometry and electronic structure properties (charges, dipole moment, polarizability, HOMO and LUMO energies) of acrylonitrile, CH2CHCN, cis- and trans-2-butenenitrile, CH3CHCHCN, 3-butenenitrile, CH2CHCH2CN, and 2-methyl-2-propenenitrile, CH2C(CH3)CN are obtained at the 3-21G level. Results on three anionic derivatives of these molecules obtained at the 3-21+G level are also reported. Properties of the molecules in their isolated states are considered as a preliminary basis to compare initial steps of bulk and surface polymerization of vinylic monomers by electrochemistry under cathodic polarization.
