nuclear magnetic resonance solid state nmr PSI-MI MI:1104 Solid-state NMR (ssNMR) does not require that the sample be soluble or form a crystal, and the approach can be used to study molecules larger than 100 kD. Solid-state NMR spectra are very broad, as the full effects of anisotropic or orientation-dependent interactions are observed in the spectrum. solid state nmr ssnmr 2011-07-06T09:23:11Z orchard
