Estimation of Ground State and Excited State Dipole Moments of (5-Amino-1-phenylindolizin-3-yl)(4-methoxyphenyl)methanone

Abstract

The fluorescence and absorption properties of (5-amino-1-phenylindolizin-3-yl)(4-methoxyphenyl)methanone were studied at room temperature in 15 solvents with dissimilar polarities. The impacts of solvent and GCRD parameters on the properties of the spectra are discussed. By utilizing the Gaussian 09 program, the ground-state dipole moments (µg) were have been measured experimentally and compared with theoretical values. After determining the ground-state dipole moments, the Kawski-Chamma-Viallet, Bakhshiev and Lippert equations were utilized to calculate the exciterted-state dipole moments (µe). It was observed that µe has been greater than the ground state for the dye. In this work, the impact of solvent on the absorption and emission spectra of (5-amino-1-phenylindolizin-3-yl)(4-methoxyphenyl)methanone was computed and estimated their dipole moments. For every molecule studied, there was a substantial change in the Stokes shift values increasing polarity.
