Abstract

The nonlinear optical (NLO) properties of the Indole-7-carboxyldehyde (I7C) have been investigated by computational and experimental (UV-VIS, Raman) data analysis. Mulliken charge analysis, molecular electrostatic potential, and UV-VIS absorption and vibrational Raman studies have been used to analyze the intra-molecular charge transfer occurrence in the probe system. Observed high value of dipole moment, linear polarizability and first order hyperpolarizability values suggest that the indole derivative may indeed have possibility to show good NLO behaviour.
