These pages contains a list of some solid-state magic-angle spinning (MAS) NMR experiments which are useful for protein solid-state MAS NMR assignment and structure calculations. For each experiment there is short description and an illustration showing the observed magnetisation transfers. The exact pathway is not described, as in many cases several pathways are possible, or the exact mechanism of magentisation transfer may not be known. In general, the atoms which are observed are shown in pink and those atoms through which magnetisation flows are shown in light blue (though there may be more than just these involved!). Magnetisation transfers which are usually only observed when longer mixing times are used, are shown in grey. An example spectrum or diagramatic spectrum shows what it should look like and particular features and considerations are highlighted. The descriptions here are very simplistic and for a full description, including pulse sequences, the reader should consult the original articles.
