Notizen:
Electronic absorption spectra of radical cations generated by steady-state and pulse radiolysis from a series of α,ω-diaminoalkanes (R2N(CH2)nNR2; n = 1-6, R = CH3 or C2H5), 1,4-dimethylpiperazine and 1,4-diazabicyclo [2.2.2] octane (DABCO) were measured. In some cases spectral evidence was obtained for an interaction between the nitrogen atoms leading to charge delocalization in the radical cation. A delayed formation of radical cations was associated with a conformational change necessary for achieving the most stable structure having a favourable conformation for charge delocalization.
