We previously reported the nmr spectrum of 1,4,7,7-tetrachloronorbornane; however, detailed analysis of the spectrum was precluded by its complexity, (8 spins). As an approach to the analysis of the nmr spectrum of 1,4,?-7-tetrachloronorbornane, we have selectively deuterated the 2-and 3positions, a

## Abstract Orientation effects of electronegative substituents on vicinal carbonβproton coupling constants are studied in 1,2βdisubstituted propanes and are found to resemble those on vicinal protonβproton coupling constants. Known relations for the orientation effect of substituents on synclinal
The influence of 2-hydroxy-3-[(2-hydroxy-1,1-dimethylethyl)amino]propane-1-sulfonic acid (AMPSO HL) on systems containing copper(II) was studied by glass-electrode potentiometry (GEP) and direct-current polarography (DCP), at fixed total-ligand-to-total-metal-concentration ratios and various pH valu
