Changes in solvent polarity and the concentration of added anionic surfactant on the chemical shifts and on the shape of signals of aromatic and heterocyclic protons in a series of N-methylnicotinyl and N-methylisonicotinyl esters were studied. It was concluded that mixed and inverse micelles were formed which differently affect the proton chemical shifts.
