%X The 15N and 13C chemical shifts of eight vinamidinium and azavinamidinium cations have been determined at the natural-abundance level by means of Fourier methods. Both 15N and 13C chemical shifts reflect the electron- density distribution in the pentadienium chain, especially in the aryl derivatives in which conjugative stabilization through electron withdrawal by the substituent phenyl group is exhibited.
