## Abstract ^1^H and ^13^C NMR data for 13 nitrohistidine derivatives are reported, providing a diagnostic method for the elucidation of the __N__^1^β(**2**) and the __N__^3^βsubstituted (**3**) regioisomers. Spectral assignments of constrained surrogates of His (**4**) and of the HisβGly dipeptide
## Abstract The assignment of the signals in the ^13^C and ^1^H NMR spectra of __N__βphenylβ2,4βdimethylbutaβ1,3βdieneβ1,4βsultam is difficult for the signal pairs Cβ2 and Cβ4, Cβ1 and Cβ3, (Cβ1)ο£ΏH, (Cβ2)ο£ΏCH~3~ and (Cβ4)ο£ΏCH~3~. The ^13^C NMR spectrum recorded under gated decoupling conditions provi
