In a brief introduction, we first compare, in the framework of globular cluster dynamics, the relative importance of the amounts of information acquired, during the past decades, through proper motion and radial velocity measurements. Next, we review the most recent and important studies based on measurements of radial velocities obtained with single-object and multi-object spectrometers and interpreted with the use of King-Michie and Fokker-Planck models or with non-parametric methods. Then, we present the results obtained from integrated-light spectra in the cores of a few collapsed globular clusters. We conclude with a summary of the most important scientific outputs secured from the radial velocity measurements of stars in globular clusters.
