In science:

Also, some parameters affecting performance may only be evaluated from data that are obtained over a longer term, such as dependencies on seeing, temperature, and the effects caused by precession or nutation.
A Prototype for the PASS Permanent All Sky Survey
The nutator could only operate reliably under quiet or moderately windy conditions (a few m/s).
Evaluation of the ALMA Prototype Antennas
That implies the nutations between molecular states with various I values.
Prototype model for nuclear spin conversion in molecules: The case of "hydrogen"
If the angular momentum J does not happen to be along one of the grain’s principal axes, then the grain’s angular velocity ω will not be parallel to J, and will nutate around J, with a nutation rate that will be smaller than (but comparable to) the rotation rate.
Astrophysics of Dust in Cold Clouds
Because the rotation and nutation are both rapid, we will quickly obtain a rotation-nutation average of the grain orientation.

Comments on the ERA-2005 numerical theory of Earth rotation
The FCN frequency is critical in determining the magnitude of the nutations, and the results of past estimates of its value from fits to data have been quite robust.
Comments on the ERA-2005 numerical theory of Earth rotation
