ADF教程:如何计算分子体系的自旋-自旋耦合常数(Spin-Spin Coupling) 我们以如下两个分子为例进行测试,两个分子的中各自的两个H原子之间的自旋耦合常数J,实验值分别为约1Hz、7Hz,计算输入输出文件下载(请点击)。 下面的教程以其中第二个分子为例进行演示。 第一步:结构优化 优化过程参考,参考:如何优化分子的几何结...
In most routine applications of NMR only the magnitude of the isotropic average of the coupling constant appears, and this merely as spacings in symmetric multiplet patterns. However, the additional information which comes from the sign of the isotropic average coupling constant and the anisotropy of...
The indirect spin–spin coupling (also known as scalar or J-coupling) is an interaction between nuclear moments mediated by electrons participating in chemical bonds between the nuclei. From: Comprehensive Biomaterials, 2011 About this pageSet alert ...

We have used the second order polarization propagator method to calculate the indirect nuclear spin–spin coupling constants of13C–17O and14N–15N. We have calculated all coupling terms and the vibrationally averaged results are for CO:JFC=7.93 Hz,JSD=−3.99 Hz,JPSO=14.95 Hz,JDSO=0.10 Hz...
