Relativistic calculation of NMR spectrum parameters

狄拉克方程的解具有4x1列向量的形式，称为四分量旋量。狄拉克方程有两种解法。其中之一是两个组件的方法，其中较低的2个组件被淘汰，使用上2个组件。另一种是四分量法，即同时计算四个分量。在研究中，这两种方法都被用来评估相对论效应对核磁共振参数的影响。

A solution for the Dirac equation has a form of 4x1 column vector and called a four-component spinor. There are two methods for solving the Dirac equation. One of them is the two component method in which the lower 2 components are eliminated using the upper 2 components. The other one is the four component method in which the four components are calculated simultaneously. In the research, both the two methods are used to evaluate the relativistic effects on NMR parameters.
