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