Abstract
A rather complete data set for 12 characteristics of 18 common benzoβfused heterocycles yields two significant principal components. The loadings of the characteristics show a close correlation with those found for the same characteristics of monocyclic heterocycles. The scores for each bicycle are also closely related to those for the corresponding monocycle. The method demonstrates considerable predictive power.

## Abstract An additional set of 23 monoheterocycles was subjected to AM1 calculations, and the characteristics thus determined, together with available experimental data, treated by PC analysis. Utilizing characteristic loadings previously determined for other monoheterocycles, scores for the 23 m
