P-O-B-3 linkages in borophosphate glasses evidenced by high field B-11/P-31 correlation NMR

Résumé

The long-standing debate about the presence of P-O-B-3 linkages in glasses has been solved by high-field scalar correlation NMR. Previously suggested by dipolar NMR methods, the presence of such species has been definitively demonstrated by B-11(P-31) J-HMQC NMR techniques. The results indicate that borophosphate networks contain P-O-B-3 bonds and thus present a higher degree of atomic homogeneity than previously thought.
