Abstract: | The UV–vis spectra of α-nitrocyclohexanone were determined at 25 °C in a series of solvents, including room-temperature ionic liquids, water and CH3CN/CHCl3 binary mixtures. A multiple linear regression analysis was performed by applying the Catalán empirical multiparameter solvent approach. Polarizability plays the major role in the solute-solvent interactions, as demonstrated by the quantification of the single solvent contributions, while an excellent linear correlation was found between the experimental and calculated solvent-dependent maxima adsorption bands. The solvatochromic trend of α-nitrocyclohexanone in the investigated media was confirmed by applying the Spange empirical solvent parameters for the ionic liquids in the Kamlet–Taft scale. |
