Abstract

By the multiple-pulse method WAHUHA and the combination WAHUHA and magic-angle sample spinning the 1H chemical shift anisotropy∆S and its spatial average \( \bar G \) was measured for powders of calcium sodium hydrogen silicate (1), barium dL hydrogen silicate (2), dicalcium silicate hydrate A (3). dicalcium silicate hydrate B (4) and xonotlite (5). The values of ∆S and \( \bar G \) depend on the strength of the hydrogen bonding and are in qualitative agreement with the theoretical results of Ditchfield et al.
