Proton NMR. spectra of purine, adenine, guanine and methylsubstituted guanines have been measured in CF 3 COOH, FSO 3 H and FSO 3 HSbF 5 SO 2 at 27° and low temperatures. These conditions permit to study multiple protonation of purines, using chemical shifts of CH, NH and OH protons. The spectra of mono‐, di‐ and tri‐cations are described and fully assigned.
