Abstract

The notion of the parity of Kekule structures is discussed.
A necessary and sufficient condition for the separability of Kekule
structures into odd and even is given. It is also shown that there
are po~sible certain molecules with a nori-alternant topology, the
Kekule structures of which cannot be separated. The synthesis of
such compounds would be of interest.
