| 摘 要： | 描述了一类新的二维旋转边带分解实验,准备期包括交叉极化、若干个以TOSS序列的延迟加上的π脉冲和一个π/2脉冲,混合期包括一个π/2脉冲和一个TOSS序列,在演化期内,磁化矢量位于z方向。本实验能给出完全分解的各向同性化学位移与各向异性化学位移,它与Kolbert等人[5]的实验方法相互补充。 |

| Abstract: | In this paper, we describe a new type of two-dimensional resolved MAS experiments involving a preparation period utilizing cross polarization, several π pulses applied at the TOSS timings and a π/2 pulse, an evolution period in which the magnetization vector is in the z axis and a mixing period composed of a π/2 pulse and a TOSS sequence. The experimental schemes proposed in this paper can yield a complete separation of isotropic and anisotropic chemical shifts, which is a complementary method to the Kolbert's experiment[5]. |
