| Abstract: | The influence of chemical shift anisotropy on 2D NMR nutation of quadrupolar nuclei with half integer spin is considered in the present work. Hamiltonian matrices during the period of evolution time of 2D NMR nutation is diagonalized with numerical method.Powder average is made with the method of tent. The spectra of 2D NMR nutation for spin I=3/2, 5/2, 7/2, and 9/2 were obtained. Experimental results are in agreement with theoretical calculations. |
