## Abstract ^1^H and ^13^C NMR spectra are reported and assigned for imidazo[1,2‐__a__] pyrazine and for __N__‐1‐methyl‐ and __N__‐7‐methyl‐imidazo[1,2‐__a__] pyrazinium iodides. The effect of protonation on the chemical shifts of the parent molecule is demonstrated, and through the use of ^13^C an
