## Abstract A rather complete data set for 12 characteristics of 18 common benzo‐fused 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

## Abstract Restudy of an almost complete data set of 12 characteristics for 16 common heterocycles confirms the previous conclusion [1] of the independence of „classical”︁ and of „magnetic”︁ aromaticity. The scores for the individual heterocycles correlate well with their chemical structure.

## 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
