J.Hiet, M.Deschamps, N.Pellerin, F.Fayon, D.Massiot, 'Probing chemical disorder in glasses using silicon-29 NMR spectral editing', Phys. Chem. Chem. Phys. 11 6935–6940 (2009) doi:10.1039/b906399d

Chemical disorder can be characterized in silicate glasses using spectral editing in 29Si solid-state NMR. Strongly overlapping lines from the Qn(mX) (i.e. Si(OX)m(OSi)n-m) molecular motives in the glass 29Si solid-state NMR spectrum can be quantified using the 2J(29Si-O-29Si) scalar coupling and 2 to n-quantum filters in INADEQUATE-like experiments, without prior knowledge of referenced chemical shifts, offering a new probe for the microscopic origins of residual entropy in glassy materials.
