## Abstract Methylation of 1,__N__^6^‐ethenoadenosine (εAdo) gives a mixture of N1‐ and N9‐quaternized methyl‐3‐β‐D‐ribofuranosylimidazo[2,1‐__i__] purinium salts (m^1^εAdo^+^ and m^9^εAdo^+^, respectively). The ratio of the two forms of the protonated εAdo [H^1^εAdo^+^]/[H^9^εAdo^+^] has been esti
