Abstract
IT has been known for some time that hydrogenbonded crystals such as quinol and urea can enclathrate a variety of molecules. Many studies of the structures of clathrates by X-ray diffraction1–4 and infra-red spectroscopic techniques5 have yielded little information about the motions of the enclathrated molecules. In special cases, for example, oxygen and nitric oxide enclathrated in quinol, where the trapped molecule is paramagnetic, magnetic susceptibility measurements6–8 have indicated that the trapped oxygen and nitric oxide molecules behave rather like free gas molecules.
