We study spin-rotation effects in a magnetic molecule bridged between two conducting leads. The dynamics of the total angular momentum couples spin tunneling to the mechanical rotations. The Landau-Zener spin transition produced by the time-dependent magnetic field generates a unique pattern of mechanical oscillations that can be detected by measuring the electronic tunneling current through the molecule.
