Rough indications that v sin i is correlated with peculiar velocities exist only in the range of early-type Be Stars. Further corrections of space velocities of Be Stars for systematic movements of stellar groups to which they belong, as well as identifications of coeval stars have to be performed in order to decide whether the high rotation of some of them could be the consequence of gravitational encounters.
