摘要：

The absorption and fluorescence spectra of newly synthesized thiadiazole derivative namely 6-(4-chlorophenyl)-2-(naphthalene-1-ylmethyl) imidazo [2, 1-b][1,3,4] thiadiazole [6CNMT] have been recorded in various solvents of different polarities. The ground state dipole moment of 6CNMT was obtained from quantum chemical calculations. Solvatochromic correlations were used to estimate the ground state (mu(g)) and excited state (mu(e)) dipole moments. The excited state dipole moments are observed to be greater than the ground state dipole moment. Further, the changes in dipole moment (Delta mu) were calculated both from solvatochromic shift method and microscopic solvent polarity parameter (E-7(N)) and the values are compared. The spectral variations were also analyzed by Kamlet-Taft parameters.
