这种方法的原理是：调节强度调制器的偏置使其抑制奇数阶谐波的产生，同时使激光器工作在二阶有理数锁模状态，最后用一个光纤光栅消除载波。

By using CP-TOSS NMR method to suppress the spinning sidebands, 13C isotropic chemical shift of the above complexes was thus obtained. While in the 2D-PASS NMR spectra, spinning sidebands related to chemical shift anisotropy remain and are well-separated according to their orders. The principal components of the 13C chemical shift tensors were then extracted by fitting the experimental intensities of 13C spinning sidebands with Mathematic programs.
