The influence of aprotic and protic solvents that are used on the dipole moments and absorbance as well as emission spectra of the Eosin Blue have been carefully examined in an assortment of solvents. The dipole moment can be discovered to have a higher level of excited state than in the ground state. The ground state and excited state dipole moment were computed experimentally using the salvatochromic shift in the emission and absorption spectra associated to the dielectric constant (ε) and refractive index (n). In various solvents, the Stokes shift was investigated for the Eosin blue molecule. For the solvents utilized, this causes the molecule to be compared to the ground state, the excited state is more polar.
