## 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
Trifluoromethane (CHF 3 ) has been studied using 1 H, 13 C and 19 F NMR spectra in the gas phase at 300 K. For the first time all the spin-spin couplings and 13 C shielding of CHF 3 were measured as functions of density. After extrapolation to the zero-density limit the appropriate shielding ( 1 H,
