Study on the cross conjugation effect of fork conjugated system of nitrogen bridge using AM1. The results of AM1 indicate that two components of HOMO, aromatic cycle and formyl polyenic, are relative to the form of conjugation in the model compounds. In the two sides of nitrogen bridge, the degree of conjugation of one double bond with one formyl polyenic group is about equal to two aromatic cycles.
