NMR张量作为三维分子模型表面的表示是一种信息丰富的表示,突出了张量主成分与底层分子和电子结构之间的几何关系。在这里,我们描述了一个新的计算工具,TensorView,用于描绘NMR张量的分子框架。该软件包利用Mathematica编程环境中的图形界面和内置的分子显示功能,并且对于显示来自广泛的商业和用户特定计算化学软件包的张量性质是鲁棒的。两个数学形式表示张量相互作用表面,流行的椭球形构造和技术上更正确的“卵形”的形式。例子提供了化学屏蔽和位移张量,偶极-偶极和四极耦合,和原子各向异性位移参数(热椭球)来自NMR晶体学。
The representation of NMR tensors as surfaces on three-dimensional molecular models is an information-rich presentation that highlights the geometric relationship between tensor principal components and the underlying molecular and electronic structure. Here we describe a new computational tool, TensorView, for depicting NMR tensors on the molecular framework. This package makes use of the graphical interface and built-in molecular display functionality present within the Mathematica programming environment and is robust for displaying tensor properties from a broad range of commercial and user-specific computational chemistry packages. Two mathematical forms for representing tensor interaction surfaces are presented, the popular ellipsoidal construct and the more technically correct “ovaloid” form. Examples are provided for chemical shielding and shift tensors, dipole-dipole and quadrupolar couplings, and atomic anisotropic displacement parameters (thermal ellipsoids) derived from NMR crystallography.
