Abstract
The transition from the dynamics of isolated molecules to that of a bulk liquid is observed for the first time by analyzing the dielectric relaxation (10-2–109Hz) of ethylene glycol (EG) guest molecules confined to zeolitic host systems of different topology. Beyond a threshold channel size the liquid character is lost, indicated by a dramatically increased relaxation rate and an Arrhenius-like temperature dependence. Computer simulations of the molecular arrangement in a confining space prove that an ensemble as small as six molecules is sufficient to exhibit the dynamics of a bulk liquid.
