Abstract: The theoretical considerations of the molecular hyperpolarizabilities of donor acceptor substituted aromatic molecules show that the transfer of a proton from the electron-donor group of an acid HO-C6H4-CHCH-C6H4-NO2(OSN) to the electron acceptor group of a base Me 2N-C6H4-CHCH-C5H4N(DAMS) could significantly increase β and γ for both resulting ionic species relative to the corresponding neutral molecules by using ZINDO SOS, FF/PM3 and CPHF/PM3 three methods.

Key words: Proton transfer, The first order hyperpolarizabilities, The second order hyperpolarizabilities, ZINDO SOS, FF/PM3, CPHF/PM3
