HSQC experiments are the most basic experiments in protein NMR. In HSQC experiments, water suppression is mainly achieved by a pair of field gradient pulses whose intensity ratio is in accordance with the ratio of the heteronuclear gyromagnetic ratios. In this paper, a simple method is propsed to achieve clean water suppression in HSQC experiments by properly modulating the gradient pulse length.
