โฆ Synopsis
Two 2D experiments, novel to solid-state NMR, are demonstrated using the trimethylsilyl ester of cubic octameric silicate (Q8M8). J-Resolved 13C NMR with BLEW-12 proton homonuclear decoupling reveals the scalar 13C-1H couplings and 29Si SUPERCOSY the connectivities of silicon atoms in the distorted Q8 cube.
