The underlying relation between the magic-angle turning (MAT) and phase-adjusted spinning sidebands (PASS) experiments is examined. The MAT experiment satisfies the PASS conditions for separating spinning sidebands with a non-constant total evolution time and only requires linear t(1) increments of up to one rotor period. The time-domain data of the two experiments are related by a shearing transformation. A combination of the linear evolution-time increments of MAT and simple data processing of PASS are particularly attractive for the implementation of MAT for measuring chemical shift anisotropy.
检查了魔角旋转（MAT）实验和相位调节旋转边带（PASS）实验之间的内在关系。MAT 实验满足了用非恒定总演化时间分离旋转边带的 PASS 条件，并且只需要线性增加 t(1)，最多增加一个转子周期。两个实验的时域数据通过剪切变换相关联。MAT 的线性演化时间增量和 PASS 的简单数据处理的组合对于实现用于测量化学位移各向异性的 MAT 特别有吸引力。
