NMR detection and conformational dependence of two, three, and four-bond isotope shifts due to deuteration of backbone amides
{{output}}
NMR isotope shifts occur due to small differences in nuclear shielding when nearby atoms are different isotopes. For molecules dissolved in 1:1 H2O:D2O, the resulting mixture of N-H and N-D isotopes leads to a small splitting of resonances from adjacent nuclei... ...
