Abstract: The geometry, electronic structures and electronic spectra of trans-stilbene derivatives are systematically studied by PM3 and INDO/CImethods. On the basis of correct UV-Vis spectra, the position and strength of the two photon absorption cross-sections can be predicted. We deviced a program of Sum Over-States expression and calculated the nonlinear third-order optical susceptibilities and two photon absorption cross-sections by it. The influences of various substituents on two photon absorption cross-sections are discussed micromechanically.
