WebNational Center for Biotechnology Information The HSQC provides the correlation between the nitrogen and amide proton, and each amide yields a peak in the HSQC spectra. Each residue (except proline) therefore can produce an observable peak in the spectra, although in practice not all the peaks are always seen due to a number of factors.
