Abstract

Abstract: Studies of aprotic solvent effects on substituent fluorine nuclear magnetic resonance (F nmr) shifts of p-fluorophenyl labeled systems have provided evidence of general significance regarding the nature of solvation of molecules. The correlation of the aprotic polar solvent F nmr shifts with the UI parameter of the substituent and the ET solvent polarity parameter is shown to be highly general. It is concluded that local fields of aprotic ...
