Experimental detection of multiple-quantum coherence transfer in coupled spin solids by multi-dimensional NMR experiments.
Three-dimensional multiple-quantum coherence experiments in coupled 1/2 spin solids have been designed to directly detect coherence transfers among all the accessible coherence orders during irradiation. The experiments have been performed on the coupled four-spin polycrystalline sample 1,2,3,4-tetrachloronaphthalene-bis(hexachlorocyclopentadiene) adduct. The experimental results reveal how the coherences transfer in this spin system, which support the theoretically deduced selection rules and can be used to assist more precise description of multiple-quantum coherence dynamics.
