19F and 1H magnetic relaxation dispersion determination of the translation encounter between ionic salts and nitroxide free radicals in aqueous solution

A study was conducted to analyze the translation encounter between ionic salts and nitroxide free radicals in aqueous solution. Relaxation time measurements were carried out as a function of magnetic field strength. The pH was adjusted based on the aliquots of dilute acid or base. Results indicated that magnetic relaxation data is not enough to generate a detailed characterization of local electrostatic fields between solutes.
