Abstract

In the case of a number of N-(pyridyl)-pyrrole derivatives a linear relation was found between the PMR chemical shifts of the olefmic and aromatic protons and the adjacent carbon net charges. The Charge distribution was obtained as a sum of σ- and π-parts, calculated by the Del Re and PPP methods, respectively. Steric effects were treated on the basis of chemical shift anomalies.
