Jahn-Teller effects can result in 'pseudorotation', which is
rotation of a distortion. This should not be confused with rotation
of a real molecule. An example for C60 is illustrated
below. One carbon atom has been coloured red to guide the eye.
Pseudorotation Note how the shape of
the distortion rotates clockwise but the atom coloured red
simply moves up and down. This is further shown by the snapshots
below.
Real rotation Note how the atom coloured red
rotates around as the shape of the distortion rotates. This
is also shown by the snapshots below.
