## Abstract The substituent influence on the ^1^H and ^13^C NMR chemical shifts in 2โ€substituted benzimidazoles and their anions and cations has been investigated. The transmission of the electronic effects of substituents from Cโ€2 to Cโ€5 (6) is approximately 20% less effective than that in the opp

## Abstract The influence of substituents on the ^13^C NMR chemical shifts of 2โ€substituted 1โ€methylbenzimidazoles has been investigated. The electronic effects of the substituents are transmitted to Cโ€4 and Cโ€7 mainly by the resonance mechanism, and to Cโ€5, Cโ€6 and __N__โ€CH~3~, by approximately eq
