Abstract
Lattice diffusion at 343 K of β-naphthol-8 14C into naphthalene single crystals has been measured by means of the microtome sectioning technique. Four crystallographic directions of diffusion have been studied, with two to four experiments for each of them to attain exact precision. From these data the diffusion tensor has been determined. It shows a pronounced anisotropy of the mobility of the tracer molecule into the naphthalene lattice. A geometrical analysis of the different types of jumps into the crystalline structure of naphthalene furnishes first elements for the understanding of this anisotropy.Keywords
