核磁共振谱可用于识别旋转超流体3He-A序参数场中不同的拓扑物。我们将它们的特征列在CW核磁共振吸收线形中。量子化的涡旋线、磁区壁和它们的组合，即涡旋片，都会在核磁共振谱中产生具有特定强度和频移的卫星峰。给出了光谱的例子，以允许比较和区分不同的对象。
NMR spectrometry can be used to identify different topological objects in the order parameter field of rotating superfluid3He-A. We list their signatures in the cw NMR absorption line shape. Quantized vortex lines, domain walls, and their combination, the vortex sheet, all induce satellite peaks with specific intensities and frequency shifts in the NMR spectrum. Examples of spectra are presented to allow a comparison and to distinguish between different objects.
