## Abstract The substituent influence on the ^1^H and ^13^C NMR chemical shifts in 2βsubstituted benzimidazoles and their anions and cations has been investigated. The transmission of the electronic effects of substituents from Cβ2 to Cβ5 (6) is approximately 20% less effective than that in the opp
