Abstract

23Na and 23Na/19F double resonance MAS NMR methods have been used to study the binding of hydrofluorocarbon-134 (CF2HCF2H) in zeolites NaY and CsY. The interaction of HFC- 134 with the sodium cations is so strong that the sodium cations in the sodalite cages (site I') migrate into the supercages to bind to the hydrofluorocarbon molecules.
