High-resolution proton nuclear magnetic resonance spectra of the tetrachlorinated through beptachlorinated dibenzo-p-dioxins are presented. Chemical shifts from dioxins that were synthesized separately are used to assign congeners formed in mixtures. Linear multiple regression analysis was applied t
## 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
