## Abstract The introduction of a substituent in the 3βposition of the pyrrole ring in __N__βvinylβ2βarylpyrroles and β2βheteroarylpyrroles results in an increase in the dihedral angles between the planes of the pyrrole ring and the aryl (or heteroaryl) residue, and a decrease in the dihedral angle

## Abstract ^1^H and ^13^C nmr spectra of several __N__β and Cβsubstituted carbazoles (Series 1, 2, 3 and 4) were measured. Correlations between chemical shifts and substituent constants show that these parameters describe properly the substituent effect on the nmr phenomena. Atomic charge densitie
