Abstract

We report the first B-10 NMR experiments on borate glasses and related polycrystals using modern, fixed field, pulsed NMR in combination with a secondary field sweep coil. All six transitions from the I=3 nucleus could be observed. The spectra obtained have been compared with those simulated using third order perturbation theory and we have determined the quadrupole parameters for B-10 in various systems with a precision which is more than an order of magnitude improved when compared with values reported to date from central transition B-11 MAS NMR. The program used to simulate the data also allows a distribution of quadrupole parameters to be fitted for each distinct site, thus taking into account the distribution of environments for a given site in a glass.
