## Abstract Nitrogenβ14 nuclear quadrupole resonance frequencies at 77 K are reported for a series of carbazole compounds including __N__βvinylcarbazole. Differences in charge distribution between pyrrole and carbazole are explained on the basis of delocalization of pi electrons. Effects of the ald
