A study of the correlation of solvent effects on the chemical shifts of the methyl protons of sylvan, toluene and α‐picoline led to the conclusion that the preferential site of solvation of the furan ring in acidic solvents is the π‐electron cloud and not the n‐electron orbital of the oxygen atom.

The use of chemical probes for the characterization of chemical properties is explored for aprotic binary solvent mixtures. The solvatochromic indicators N,N-diethyl-4-nitroaniline, 4-nitroanisole, 4-nitroaniline and 4nitrophenol were used to characterize binary solvent mixtures of a polar aprotic h
## Abstract The semi‐empirical SCF MNDO method has been used to calculate the radical reactivities for each reaction site in some neutral furan molecules as the average of the HOMO and LUMO probabilities both in 2p~z~ atomic orbitals1SCF: Self‐consistent field; MNDO: modified neglect of differentia
The preferential solvation of neutral and ionic organic species (phenol, nitroanilines, N-methylbutyramide, 1,4-dioxane, acetate and tetraalkylammonium ions) in binary solvent mixtures (aqueous CH 3 CN, DMSO, EtOH, 1-PrOH, CH 3 CON(CH 3 ) 2 ; CH 2 Cl 2 /Et 2 O; 1,4-dioxane/benzene; cyclohexane/THF)
## Abstract ^23^Na‐chemical shifts for the NaClO~4~ solute depend markedly upon the composition of binary solvent mixtures of THF with amines (pyridine, piperidine, pyrrolidine, aniline, propylamine, and isopropylamine). These changes, analyzed in a novel application of the __Hill__ formalism, show
