  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.
