DIFFUSION IN ORGANIC CRYSTALS

Abstract

This report describes the determination of the self-diffusion coefficient in anthracene crystals as a function of temperature and crystal orientation. Thermodynamic quantities associated with the diffusion process were evaluated and are discussed. The origin of an unusually long tail of diffusant concentration is considered in terms of a secondary fast diffusion process. Errors introduced by the experimental procedure are estimated.
