摘要
本文提出了用量子力学的空间转动变换算符描述特形脉冲的方法。它把任意的特形脉冲用三个欧拉角来表示,并且使得在特形脉冲下的相干演化可以很容易地利用多极NMR理论,张量算符理论或者积算符理论来分析,作为例子,用数值方法计算了高斯脉冲的三个参数。
he propagator of a shaped pulse is taken as the rotation operator with the threeEuler angles. The coherence evolutions under the shaped pulse are described by MultipoleNMR , the tensor operator formalism, and the Cartesian operator formalism. The nu-merical calculation for a Gaussian-shaped pulse is made as an example.
