Notizen:
More than 100 solvents and the gas phase were used to develop a solvent dipolarity-polarizability scale that combines the medium dipolarity and polarizability into a single parameter (SPP) calculated from the UV-visible spectra of 2-(dimethyl-amino)-7-nitrofluorene (DMANF) and its homomorph 2-fluoro-7-nitrofuorene (FNF). The proposed scale compares favourably for nonprotic solvents with existing solvent polarity scales including Kosower's Z, Dimroth and Reichardt's ET(30), Brooker's χR, Dong and Winnick's Py; Kamlet, Abboud, and Taft's π*, and Drago's S′ scale. When data are derived from electronic transitions, they provide an accurate description for the solvent effect in UV-Vis, IR, NMR, and fluorescence spectroscopy as well as in other chemical areas including thermodynamics and kinetics.
