✦ Synopsis

Separation of the Energetic and Geometric Contribution to the Aromaticity. Part 9. Aromaticity of Pyrazoles in Dependence on the Kind of Substitution.

-Based on crystal and molecular structure data of the fused pyridines (I) and RHF/6-311G ab-initio calculations for some pyrazole derivatives it is found that an increase of the double bond character of the exocyclic bonds causes a decrease of aromaticity of the pyrazole ring. -(KRYGOWSKI, T.
