Formation of deep gas traps in glassy n-butanol

Abstract

The capture of oxygen molecules by deep traps during oxygen diffusion in butanol glasses has been studied at 90 K using the kinetics of the tert-butyl radical oxidation. It is concluded that the traps are certain molecular structures that are the equilibrium entities of the supercooled liquid in a temperature domain centred about 140 K and above the glass transition point (118 K).
