要旨

Broadband dielectric spectroscopy (10^-2Hz - 10⁹Hz) is employed to study the molecular dynamics of the simple glassforming liquid ethylene glycol (EG) being confined to zeolites of varying size and topology. A sharp transition is observed from a single molecule dynamics (with an Arrhenius-type temperature dependence) to that of a liquid (with a temperature dependence of the mean relaxation rate according to a Vogel-Fulcher-Tammann-law (VFT-law)): While EG in silicalite and H-ZSM-5 (showing a single-molecule relaxation) has a coordination number of four, EG in zeolite beta or AIPO₄-5 has a coordination number of five and behaves like a bulk liquid.
