Abstract
Precise rotational velocities have been determined for 12 lithium-rich giant stars using the CORAVEL spectrometer. Except for HD 9746, the l ithium-rich giants show normal rotational velocities with respect to t ypical lithium-normal giants of the same spectral type. Further, we ha ve found no sign of binarity for the lithium-rich giants.
