摘要
本文基于化学位移加和性理论,建立了一个经验公式,利用所得公式计算了9个化合物的δ_C值,计算值与文献值符合良好,并对32个化合物的^(13)C NMR化学位移进行了预测。
Emperical formulas were set up according to the additive theory of chemical shift in this paper. The chemical shifts of 9 quinoline alkaloids were calculated using the proposed emperical formula. Calculated and experimental shifts are in excellent agreement. The chemical shifts of 32 compounds were predicted in addition.
