Abstract: | Distinct EPR signals are observed for the free and included species for the inclusion of the neutral benzyl tert-butyl nitroxide probe into a calix4]arene host in water (shown schematically). Computer simulation of the EPR spectra recorded at various temperature enabled direct determination of the activation and kinetic parameters for this inclusion process. |
