摘要
蛋白质NMR中最基本的实验是HSQC实验.在HSQC实验中,水峰压制的主要方法之一是利用一对与异核旋磁比比值相适应的梯度脉冲.该文介绍一种简单易行的方法,只需对这一对脉冲进行适当的延长便能使得水峰几乎完全消失.
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.
