Different chemical groups have different chemical shifts. This is one of the major information sources in NMR spectra. In proteins, for example, the signals of H N, H alpha, aromatic and aliphatic protons can be distinguished by their chemical shift. http://leah4sci.com/organicchemistry Presents: H-NMR How To Analyze PeaksAre you struggling with organic chemistry?

The three-dimensional conformations adopted by a free ligand in solution impact bioactivity and physicochemical properties. Solution 1D NMR spectra inherently contain information on ligand conformational flexibility and three-dimensional shape, as well as the propensity of the free ligand to fully preorganize into the bioactive conformation.

When submitting to the FDA or other regulatory agencies, full structural characterization by NMR provides crucial evidence of compound identity. NMR screening techniques, such as SAR by NMR, RAMPED-UP NMR, STD-NMR, and NMR-SOLVE (Table 1), were developed to identify ligands that bind a therapeutic target in a biologically relevant manner by observing chemical shift changes in two-dimensional (2D) 1H-15N HSQC spectra.
