Abstract : The effect of a crystalline porous adsorbent on the magnetic properties of absorbed atomic hydrogen was investigated by ESR techniques. The decrease of the hyperfine structure splitting constant is attributed to interaction forces, mainly of the van der Waals type, at the gas-solid interface. The hyperfine interaction tensor is evaluated using the weak field E as a perturbation and assuming a simplified model for the hydrogen-solid system, where the surface forces are represented by a uniform electric field. The anisotropy in the ESR spectrum of the absorbed hydrogen is accounted for by the theoretical treatment developed, and a rough estimate of the interaction energy is obtained which is in agreement with previous, experimentally determined values.
