Abstract
N-15 NMR data are reported for the three proton sponges DMAMN, DMAMB a nd DEAMB together with some of their salts with HNO3 and HClO4. Low te mperature N-15 measurements on the monoperchlorate salts reveal the pr esence of a [N-H-N](+) structure from the values observed for (1)J(N-1 5-H-1). The diperchlorate salts show monoprotonation of each nitrogen atom.
