Limiting values of the one-bond C H spin-spin coupling constants of the imidazole ring of histidine at high-pH

Assessment of the relative amounts of the forms of the imidazole ring of Histidine (His), namely the protonated (H ) and the tautomeric N -H and N -H forms, respectively, is a challenging task in NMR spectroscopy. Indeed, their determination by direct observation of the N and C chemical shifts or th...
