Molecular motion in the supercooled liquid state: Small molecules in slow motion

Abstract

It is shown that the motion of small molecules in the supercooled liquid state may occur at reorientation rates 108 to 1011 sec slower than in normal low viscosity solvents. The detailed dielectric behaviour of anthrone and nitrobenzene in supercooled ortho-terphenyl is described, and interpreted as a cooperative process. The important implications of this work in relation to the behaviour of solid polymers is briefly discussed. © 1971.
