摘要
The results of high-level nonempirical quantum-chemical calculations of C-13-C-13 coupling constants in twelve heteroaromatic ketone oximes are well consistent with the available experimental data. In all the examined compounds, the effect of the unshared electron pair on the oxime nitrogen atom on J(CC) strongly predominates over conformational and electronic effects, which makes it possible to unambiguously assign J(CC) values to different configurations.
