Changes in the 'H and "C NMR spectra over the temperature range -30 to +6OO"C are used to investigate conformational isomerism in N,N'-dimethylpiperazine, the N,N,N',N'-tetramethylpiperazonium dication and trialkylpiperazonium monocations of the type MeN(CH2CH2),N(Me)R+, where R = Me, Et, n-Pr, i-Pr
