Popis: |
The contributions from anisotropic magnetic screening and electronic effects to the relative chemical shifts of the NH protons in the amides and N,N-dimethylhydrazides of succinic and glutaric acids were calculated. It was shown that the splitting of the signals of the NH protons is largely determined by the redistribution of electron density in the molecule during the conformational transition. |
