Using the Anderson-Weiss (AW) formalism, analytical expressions of the NMR signal are obtained for the following magic-angle spinning (MAS) experiments: total suppression of sidebands (TOSS); phase adjusted spinning sidebands (PASS); rotational-echo double-resonance (REDOR); rotor-encoded REDOR (REREDOR); cross-polarization magic-angle spinning (CPMAS); exchange induced sidebands (EIS); one-dimensional exchange spectroscopy by sideband alternation (ODESSA); time-reverse ODESSA (trODESSA); centerband-only detection of exchange (CODEX). In order to test the validity of the AW approach, the Gaussian powder approximation is compared with exact powder calculations. A quantitative study of the effect of molecular dynamics on the efficiency of the TOSS and REDOR pulse sequences is then presented.

几个幻角旋转NMR实验的解析解。

使用Anderson-Weiss(AW)形式主义,可以为以下魔术角旋转(MAS)实验获得NMR信号的解析表达式:完全抑制边带(TOSS);相位调整旋转边带(PASS);旋转回波双共振(REDOR);转子编码的REDOR(REREDOR); 交叉极化幻角旋转(CPMAS); 交换感应边带(EIS);通过边带交替进行一维交换光谱(ODESSA);时间倒转的ODESSA(trODESSA);仅中心带的交换检测(CODEX)。为了测试AW方法的有效性,将高斯粉末近似与精确粉末计算进行了比较。然后提出了分子动力学对TOSS和REDOR脉冲序列效率影响的定量研究。
