Resonance assignment in proteins

Resonance assignment in proteins. in order to be able to actually solve the structure of a protein, we first have to assign the spectrum. Each peak corresponds to some 1 H nucleus within some amino acid residue. The sharp peak at -0.8 ppm is almost certainly a methyl.
