Determination of ground and excited state dipole moments of some naphthols using solvatochromic shift method

► Dipole moments for 1 and 2-naphthols are estimated from solvatochromic shift. ► For 1-naphthol, the values in aprotic solvents are much less than those in presence of protic solvents. ► The study underlines the presence of specific interaction in protic solvents.
