  ABSTRACT: The optimized geometric structure and photophysical properties of 6-Amino-2-methylpyridine-3-carbonitrile dye have been studied by using Density Functional Theory (DFT). The lowest singlet excited state geometry optimized using Time-Dependent Density Functional Theory (TD-DFT). On the basis of ground and excited state geometries, the absorption spectra have been calculated using the DFT and TD-DFT method in gas phase and acetonitrile medium. To understand the Non-Linear Optical properties of 6-Amino-2-methylpyridine-3-carbonitrile dye, we computed dipole moment (μ), electronic polarizability (α), and first hyperpolarizability (β0) and second order hyperpolarizability (γ) using B3LYP density functional theory method in conjunction with 6-311++G(d) basis set.
