The "N NMR chemical shifts of ten substituted pyridines (B) and their complexes with trifluoroacetic acid (AHB) were measured at the natural abundance level in dichloromethane. The plot of the relative chemical shifts [A6("N) = G(AHB) -6(B)] against ApK, gives a titration curve which reflects a prot
