Abstract

Topological resonance energies of coumarin and the following
derivatives: 3-hydroxycoumarin, 4-hydroxycoumarin, 3,4-dihydro-.
xycoumarin, 4,6-dihydroxycoumarin, 4,5,7-trihydroxycoumarin, 3-
-carboxy-4-hydroxycoumarin, 3-bromo-4-hydroxycoumarin, and
6-bromo-4-hydroxycoumarin, are reported. Theoretical predictions
that these all coumarins should exhibit aromatic properties are
sustained by the ample experimental evidence. In addition, coumarin
and isocoumarin are predicted to be much more stable than
the corresponding quinonoid isomer.
