Sažetak

Isomeric bicyclic conjugated systems consisting entirely of
five-membered heterocycles were studied using a novel aromaticity
index named topological resonance energy (TRE). TRE has correctly
predicted the aromatic behaviour of all the groups of isomers
studied. (These isomers called positional isomers because they
formally differ only by the position of a-bivalent heteroatoms)
may be classified into a particular group according their annelation
mode, which closely parallels TRE predictions and experimental
findings.
