Key Laboratory of Computer Chemistry, Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences.Shanghai(200032)Abstract : The most usual problems encountered in the structure handling are tautomerism, alternating and aromatic systems. Though a number of methods have been reported in the literature, a common disadvantage is that only the convenience for processing were taken into account, but their chemical sense was rarely considered.
