ABSTRACT
Schiff bases of 2-aminopyrimidine and 2-aminopyrazine with benzaldehyde and its derivatives have been prepared and investigated by IR, UV and 1H-NMR spectroscopy. The results are discussed in terms of molecular structure and substituent effects. It is found that the CH=N linkage is coplanar with the benzal ring. The ionization potentials of the Schiff bases are determined using absorption spectra
