Structural interpretation of non-exponential hydrogen transfer in glassy methanol

The non-exponential time dependence of hydrogen abstraction by methyl radicals in a methanol glass is reinvestigated and explained as due to a narrow random distribution of hydrogen tunnelling distances. Possible implications for other non-exponential relaxation processes in non-crystalline materials are briefly discussed. \ua9 1985.Peer reviewed: YesNRC publication: Ye
