Here we report the detailed measurement of long-range heteronuclear spin-spin coupling constants, especially 2, 3JCH spin-spin couplings for eight different cyclopentane derivatives. These 2, 3JCH constants were shown to be a useful tool in the determination of the relative stereochemistry in these rings. The coupling constant measurements reported here are based on two different experiments: a 2D heteronuclear correlation experiment named G-BIRDR, X-CPMG-HSQMBC and the 2D-coupled gHSQC {1H-13C} experiment
在此，我们报告了对远程异核自旋-自旋耦合常数的详细测量，特别是针对八种不同环戊烷衍生物的2, 3JCH自旋-自旋耦合。这些2, 3JCH常数被证明是确定这些环中相对立体化学的有用工具。此处报告的耦合常数测量基于两个不同的实验：一个名为G-BIRDR、X-CPMG-HSQMBC的二维异核相关实验以及二维耦合gHSQC {1H-13C}实验
