Abstract

The potential of B-11 double rotation nuclear magnetic resonance to provide detailed structural information is demonstrated through the application of the technique to polycrystalline materials obtained by devitrification of barium diborate glasses. Isotropic chemical shift values and quadrupole interaction parameters for the four three-coordinated sites in alpha-BaB4O7 are extracted by exploiting the field dependency of the quadrupolar interaction. The technique is applied to the polymorph beta-BaB4O7, and two new barium borate materials of undetermined structure, and its role as a powerful structural probe is demonstrated and discussed.
