质子核磁共振谱的偶极魔角旋转边带强度的矩的展开(英文)

MOMENT EXPANSIONS OF PROTON DIPOLAR SPINNING SIDEBAND INTENSITIES IN A \{\}\+1H MAS NMR SPECTRUM\+*

对于包含分子和分子基团绕至少一个轴高速运动的固体体系，本文推导出其质子核磁共振谱的偶极魔角旋转边带强度的理论计算表达式，建立了用其静态粉末谱的矩的展开的计算方法，计算出旋转边带强度按三十阶矩展开的系数。

Expressions of dipolar spinning sideband intensities in a \{\}\+1H MAS NMR spectrum have been derived for a solid containing molecules and/or groups with fast axial rotation. The sideband intensities can be expanded as even moments of dipolar interactions in its static powder spectrum. The expansion coefficients up to the thirtieth moment have been carried out for practical use. It is sufficient to deal with the \{\}\+1H MAS NMR spectra with up to the fifteenth order sidebands.
