  In this paper, we analyze 10 globular clusters in order to measure their
rotational properties by using high precision radial velocity data from the
SDSS-IV APOGEE-2 survey. Out of the 10 clusters we were able to successfully
measure the rotation speed and position angle of the rotation axis for 9
clusters (M2, M3, M5, M12, M13, M15, M53, M92, M107). The comparison between
our results and previous ones shows a really good agreement within our
uncertainties. For four of the globular clusters, M3, M13, M5 and M15, we
separated the sample into two generation of stars using their [Al/Fe]
abundances and examined the kinematic features of these generations separately
from one another. In case of M3, we found significant difference between the
rotational properties of first and second populations, confirming for the first
time the predictions of several numerical simulations from the literature. The
other three clusters (M5, M13, M15) also show smaller deviation between the two
groups of stars, but those deviations are comparable to our errors.
