A distinguished triplet splitting pattern for the N-H couplings in the proton signals of a series of protonated nitrogen bases-aliphatic and aromatic amines, as well as pyridines-with the weakly coordinating tetrakis(pentafluorophenyl)borate anion, [B(CF)], is observed for the first time in nonaqueous media at room temperature. The effects of ion pairing, solvent parameters, and correlation between the δ, , and p values are reported.
