Abstract
The matrix form of TDHF theory for HP is summarized and illustrated by π-electronic applications. The description of intermolecular interaction in crystals by means of the Madelung method is given. A technique of the Lorentz tensor calculation is improved and applied to compare with the direct Hartree-Fock computation of various hyperpolarizabilities. A microscopic explanation of SHG by fullerene C60 is presented. The possibility of SHG by finite length carbon nanotubes is discussed.
