摘要：

The two topological indices sigma (recently proposed by Merrifield and Simmons) and Z (put forward by one of the present authors, Bull. Chem. Soc. Jpn., 44, 2332 (1971) are shown to be both conceptually and numerically related. For alkanes, a linear correlation exists between in ln sigma and ln Z. For unbranched catacondensed benzenoid hydrocarbons sigma and Z are linearly correlated. In any case sigma and Z exhibit a reverse dependency on molecular structures: structural transformations having an increasing effect on Z decrease sigma and vice versa.
