Abstract
The phenomenon of premelting has been investigated by proton n.m.r. in polycrystalline benzene of various purity. Our results suggest that premelting initiates at grain boundaries. The exact nature of the molten domains near the standard melting point is not yet clear but is presumably analogous to what is obtained in the surface melting experiments, i.e. a « strongly correlated interface liquid »Keywords
