摘要：

A novel molecular-graph-based structural descriptor, referred to as the Szeged index, Sz, is put forward. The Szeged index is based on distances in the molecular graph but is not of the same type as the Wiener index, W. For acyclic systems Sz and W coincide. It is known for some time that if G and G' are two catacondensed benzenoid systems with an equal number of hexagons, then W(G) = W(G') (mod 8). We now show that Sz(G) = Sz(G') (mod 8).
