Measurements were performed in several solvents and analysis of the absorption and emission wavelengths were made using Lippert's model for general solvent effects. A near linear relationship between the Stokes shift ($\Delta\bar{\nu}$) and the orientation polarizability (Δf) were observed for both 1- and 2-naphthols in most of the alkanols, thus showing evidence of a general solvent effect. However, in 1,4-dioxane-water mixtures the plots deviate from linearity indicating the dominance of specific solvent effects that are not included in Lippert's equation. In the case of interactions between the fluorophores and dioxane-water mixtures, excess Stokes' shifts are observed in the order of dioxane composition 10%>20%>30%>50%>60%>80%. This may be due to excited state proton transfer (ESPT) and the involvement of hydrogen bonding between the protic group of the fluorophore and the solvents.
