Abstract
A radiotracer study of self- and impurity diffusion in anthracene single crystals of high purity has been made using anthracene-9-14C, anthraquinone-9-14C and HO3H as tracers. Lattice self-diffusion is best described by an equation of the form D1= 1 × 106 exp –(202 kJ mol–1/RT) m2 s–1 and probably occurs by a vacancy mechanism. Anthraquinone diffuses in a manner similar to the host. Water diffuses more rapidly but has a limited solubility in anthracene. It is concluded that bulk oxidation will be small and will have little effect on the evaluation of reliable self-diffusion coefficients.Keywords
