Solid state NMR
If your sample is neither dissolved in solution nor crystallized into single crystal, solid state nmr can help you get valuable structural information. Our Bruker Avance III HD 400 MHz solid nmr system (Hg400) has three channels, capable of doing most of nuclei, especially low gamma ones. The following figure shows how 13C Cross Polarization Magic Angle Spinning (CP-MAS) solid state NMR is used to characterize the structure of the catalytically significant sites on solid catalyst surfaces ( PNAS, 2012 ) by Prof. Marks group:
