Three-dimensional nuclear magnetic resonance spectroscopy for the assignment of protein structure with nitrogen, carbon and hydrogen dimensions.
Note:
Magnetization is passed from \(\ce{^{1}H}\) to \(\ce{^{15}N}\) and then selectively to the carbonyl \(\ce{^{13}C}\) via the \(\ce{NH-^{13}CO}\) \(\rm{J}\mbox{-}\rm{coupling}\). Magnetization is then passed back via \(\ce{^{15}N}\) to \(\ce{^{1}H}\) for detection.
