Fayon, FRoiland, CEmsley, LMassiot, D2015-01-082015-01-082015-01-08200610.1016/j.jmr.2005.11.002https://infoscience.epfl.ch/handle/20.500.14299/110081WOS:000236977600008We show that triple-quantum-single-quantum (TQ-SQ) correlation spectra of crystalline and disordered solids can be obtained under MAS using pulse sequences based on through-bond J-couplings. The feasibility of the experiments in coupled spin-1/2 systems is demonstrated for fully (13)C-labelled L-alanine and Pb(3)P(4)O(13) crystalline compounds, considered as model three-spin and four-spin systems, respectively. In the case of phosphate glasses, we show that the obtained TQ-SQ correlation spectra provide an improved description of the glass forming network connectivities and of the chain length distribution in the disordered network.
