Abstract: The energy, structure and nonlinear optical susceptibilities of stable configuration several isomers of were studied by quantum chemical finite field method and semiempirical method. The effect of hydrogen bond and process of hydrogen transfer on stability of the system and nonlinear optical property was discussed. On the basis of those metioned above, the nonlinear optical susceptibilities obtained in this pater were compared with those oblained by ab initio HFmethod. As a result, the shiff base from condensation between salicylaldehyde and aniline bears a better nonlinear optical property, especially the second nonlinear optical property. This kind of compounds will become possibly a nicer optical material.
