Thermal detrapping rates of atomic hydrogen and atomic deuterium trapped in double four-ring Si8O12 cages measured simultaneously using EPR.

ABSTRACT

Does atomic hydrogen or atomic deuterium escape faster from the D4R cage of Q8M8 in thermal detrapping? An isotope effect was clearly observed by a simultaneous measurement using EPR. Arrhenius parameters were obtained and allowed the application of the absolute rate theory to explain the process.
