✦ Synopsis

A carbon-13 magic angle spinning double-quantum filtered dipolar shift correlation NMR experiment which can be used to establish through-space connectivities in solids is analyzed. The main advantage of the double-quantum filtered approach is the removal of intensity arising from natural abundance background signals. The variation in intensity of the cross and diagonal peaks observed in the two-dimensional spectrum as a function of mixing time is investigated experimentally for model systems. The observed behavior is compared with analytical expressions derived for three coupled spins, as well as with simulations based on average Hamiltonian theory. Copyright 2000 Academic Press.

A new pulse sequence for high-resolution solid-state heteronuclear double-quantum MAS NMR spectroscopy of dipolar-coupled spin-12 nuclei is introduced. It is based on the five-pulse sequence known from solution-state NMR, which is here applied synchronously to both spin species. The heteronuclear do

By combining two dipolar double-quantum (DQ) MAS experiments, a homonuclear DQ-DQ MAS exchange experiment has been designed, which probes the reorientation of dipolar tensors and allows the observation of slow molecular dynamics, in particular the determination of reorientation angles and rates.

Double-quantum filtered MAS NMR spectra of an isolated homonuclear spin-1/2 pair are considered, at and away from rotational resonance conditions. The pulse sequence used is the solid-state NMR equivalent of double-quantum filtered COSY, known from solution-state NMR. The 119Sn spin pair in [(chex3S
