spinning sidebands

https://doi.org/10.1351/goldbook.08424
Satellite peaks in a nuclear magnetic resonance spectrum symetrically spaced either side of a main peak at a frequency offset related to the rate of spinning of the sample.
Note:
In solid state nuclear magnetic resonance spectroscopy this occurs if the sample is spun at a rate less than the magnitude of the anisotropic interaction.
