摘要
Molecular mobility in organic molecular crystals was studied by means of tracer diffusion experiments : self-diffusion of naphthalene into naphthalene single crystals was measured. Three self-diffusion tensors are determined from measurements in different crystallographic directions, at three temperatures (338, 343 and 348 K). The principal axes and the anisotropy of self-diffusion are deduced. The experimental activation energies are determined and compared with results from the literature.
