✦ Synopsis

The direct measurement of reorientational rates for hydrocarbon radicals in zeolites is presented, specifically cyclohexadienyl in zeolite X, using a muon spin relaxation method. The method allows discrimination between different adsorption sites and the determination of activation energies for surface motion of the radicals.
