摘要: Abstract In anticipation of using fluctuations in the nuclear dipolar and quadrupolar interaction as a probe lithium ion motion borate glasses, static values these interactions were measured variety echo techniques. The spectrum 7 Li calculation crystalline 2 B 4 O (same chemical composition glass under study) used to estimate strength two interactions. These indicate that for 6 will be similar size dominated by unlike spin between 10 B, 11 spins. An appropriate theoretical model is proposed explicit expressions amplitude are calculated terms second moments. This single takes into account but treats an effective magnetic field. Experimental results presented which show essential validity measurements lead reasonable relative merits various techniques discussed.
