Solvent effects on the nitrogen shieldings of N,N-dimethylacetamidine (1) were found to be extremely large for the imino group (about 120 ppm) and for the amino moiety (about 50 ppm). A detailed analysis of the solvent-induced variations revealed contributions from three large interactions. These ar

NMR data, in CCl 4 , show that an increase in the concentration of cis-3-ethoxycyclohexanol (cis-3-ECH) shifts the conformational equilibrium from the ax-ax conformer (X ax-ax Z51% at 0.01 mol L K1 ), stabilized by an intramolecular hydrogen bond (IAHB), to the eq-eq conformer (X eq-eq Z67% at 0.40
