  Although numerous photometric and spectroscopic studies of stars in Galactic
globular clusters suggest the existence of several stellar generations in the
majority of clusters studied so far, kinematical properties of these stellar
generations are still relatively poorly know. In this contribution we present
first results of our study of kinematical properties of chemically-tagged
stellar populations in the Galactic globular cluster 47 Tuc. Our analysis
reveals the existence of three stellar generations in 47 Tuc that are different
in their [Li/Na] and [Na/O] ratios. Additionally, we find that the three
generations also differ in their kinematical properties: stars belonging to
primordial generation are less centrally concentrated and are kinematically
hotter than those in the subsequent generations.
