Although numerous photometric and spectroscopic studies of stars in Galacticglobular clusters suggest the existence of several stellar generations in themajority of clusters studied so far, kinematical properties of these stellargenerations are still relatively poorly know. In this contribution we presentfirst results of our study of kinematical properties of chemically-taggedstellar populations in the Galactic globular cluster 47 Tuc. Our analysisreveals the existence of three stellar generations in 47 Tuc that are differentin their [Li/Na] and [Na/O] ratios. Additionally, we find that the threegenerations also differ in their kinematical properties: stars belonging toprimordial generation are less centrally concentrated and are kinematicallyhotter than those in the subsequent generations.
