在频率为自转轴角度的磁场恒定旋转下，证明了两个相干叠加态之间的贝里相引起的频移。我们发现，在右旋的情况下，频移是for，for和for3。对于左旋，频率以相反的符号变化。频移在，和，附近为零。我们确认频移是由贝里相位的时间导数给出的，它不依赖于因子的符号。
The frequency shift induced by the Berry phase between two coherent superposition states withandwas demonstrated under constant rotation of a magnetic field with frequencyfor anglefrom the rotation axis. It was found that the frequency shift isfor,for, andforin the case of the right-handed rotation. For the left-handed rotation, the frequency changes in the opposite sign. The frequency shift is zero at, and, and it jumps byin the vicinity of. We confirm that the frequency shift is given by the time derivative of the Berry phase which does not depend on the sign of thefactor.
