Abstract
Within the theory of coupled clusters, it is proposed to use the orbital basis set of ethylene molecules in the π electron calculations of the polarizabilities and hyperpolarizabilities of conjugated systems. Test calculations show high accuracy of the method in comparison with the full configuration interaction method.
