Abstract
The kinetics and the thermodynamics of triple-ion formation involving the anion radical of 1,3,5-trinitrobenzene associated with sodium cation in tetrahydrofuran containing sodium tetraphenylborate were studied by EPR spectroscopy. All hfs-constant and line-width data and their dependence on temperature and salt concentration have been interpreted in the frame of an adequate model for ionic association. The influence of the transport properties of the solution have also been discussed. A critical analysis of the reliability and effectiveness of EPR spectroscopy in studying multiple ion associations is presented.
