In the present work, we have studied the spectroscopic properties for three newly synthesised pyridazin-3(2H)-one derivatives, using solvatochromic approaches. We have estimated the ground state dipole moments, experimentally using Guggenheim method and theoretically using the Gaussian-09 program. Excited state dipole moment was estimated using solvatochromic shift method. It is found that excited state dipole moments are larger than ground state dipole moments in all the three molecules. This may be due to the fact that, the excited states for all the three molecules are more polar than the…mehr

In the present work, we have studied the spectroscopic properties for three newly synthesised pyridazin-3(2H)-one derivatives, using solvatochromic approaches. We have estimated the ground state dipole moments, experimentally using Guggenheim method and theoretically using the Gaussian-09 program. Excited state dipole moment was estimated using solvatochromic shift method. It is found that excited state dipole moments are larger than ground state dipole moments in all the three molecules. This may be due to the fact that, the excited states for all the three molecules are more polar than the ground states.Furthermore, we have analysed the microscopic solvent polarity parameter and effect from empirical measurements of acidity (SA), basicity (SB), polarizability (SP) and dipolarity (SdP). In addition, we have estimated the fluorescence quantum yield for above said molecules using tryptophan as a standard reference in different solvents.
