Abstract: In this paper,pulsed field gradients are used to suppress the rapid-pulsing artifacts.Due to its superior homospoil charactersitic,pulsed field gradients offer an important method for removal of artifacts when data is being acquired fast compared to the relaxation times of the nuclei under study.The experimential results show that the quality of DQF-COSY spectra can be improved by the modified pulsc sequence,and the pulsed field gradients provide a good method for ultra-rapid acquisition 2D COSY-like NMR experiments with suppression the repetition rate artifacts.
