考察了化学位移各向异性对半整数自旋四极核2DNMR章动的影响．用数值方法对2DNMR章动实验的演化期的Hamiltonian矩阵进行对角化，然后用帐篷法进行粉末平均，获得了自旋为I＝3／2、5／2、7／2和9／2的四极核在不同化学位移各向异性下的2DNMR章动谱．实验结果与理论计算符合较好．
The effect of chemical shift anisotropy on the nutation of semisolid spinodal quadrupole 2DNMR was investigated. The Hamiltonian matrix in the evolutionary period of 2DNMR was numerically numerically and then the powder was averaged by the tent method. The spin I = 3/2, 5/2, 7/2 and 9/2 2DNMR Nodal Behavior of Tetrapod Nuclei under Different Chemical Shifts. The experimental results are in good agreement with the theoretical calculation.
