Theoretical and Experimental Studies of NLO Properties of New Carbazole Derivatives.

In this article we report theoretical calculations and experimental findings concerning linear optical and nonlinear optical properties of three model azo-carbazole derivative dyes. The goal of the work was to answer to what extent theoretical modeling can predict actual properties of a series of these dyes. Theoretical calculations were based on MM +, AM1 and PM3 models. Experimental data were obtained through UV-vis spectroscopy and electro-optic method. [ABSTRACT FROM AUTHOR]
