Abstract
The temperature dependent ESR spectra of NO2 adsorbed on Na-mordenite have been studied in the temperature range 77–300 K. An analysis based on slow-motional ESR theory shows that the reversible change with temperature is caused by Heisenberg spin exchange. The activation energy is 0.8–1.6 kcal/mol depending on NO2 concentration. The spin exchange is probably caused by the interaction of NO2 molecules with each other as they diffuse along the channels of Na-mordenite.
