Abstract: On the bases of AM1 and ZINDOmeth0ds, according to the sumover-states ex-pression, the nonlinear second-order optical susceptibilities βijk of a series of molecules ofbenzoquinone derivatives have been calculated. Systematic theoretical studies on the nonlin-ear optical second-order properties of benzoquinone series molecules have been performed, i.e. on the base of R'C6H4NHC6O2NH2Rindependently changing Rand R', the rule of varia-tions of β has been examined. The regularity summarized from calculated results has beenexplained micromechanica1ly.

Key words: Benzoquinone derivative, Nonlinear second-order optical property, ZINDO-SOS
