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.
