Abstract : From proton spin lattice relaxation time measurements a model for the structure and microdynamics of a benzene monolayer on graphitized carbon black is developed. The essential results are that at temperatures below - 150 °C benzene molecules are absorbed at definite sites of the graphite 0001 planes in ordered structure of hexagonal symmetry with the molecular planes oriented perpendicularly to the surface. The molecules perform reorientational jumps about diad molecular symmetry axes at a rate of 2.3 x 1013 exp- 1 060-T s-1.
