报道了外部磁场中核自旋 1/2 系统的核磁共振 (NMR) 测量和 kHz 范围内的机械旋转。核磁共振信号是通过样品和检测器线圈在旋转轴垂直于外场的条件下同步旋转来测量的。尽管系统具有单个塞曼能级分离，但 NMR 谱线还是分裂成两部分。我们分析表明，分裂起源于机械旋转下的核自旋运动，并且仅由旋转角速度决定，而无需任何材料参数。
Nuclear magnetic resonance (NMR) measurements for a nuclear spin 1/2 system in an external magnetic field and mechanical rotation in kHz range are reported. NMR signals are measured by the synchronous rotation of a sample and a detector coil under the condition that the rotation axis is perpendicular to the external field. NMR line splits into two despite the system having a single Zeeman level separation. We analytically show that the splitting originates in the nuclear spin motion under mechanical rotation, and is determined by only the angular velocity of the rotation without any material parameters.
