The kinematics of the central regions of the early-type galaxies IC5105, NGC720 and NGC7562 is studied through spectroscopic observations in the optical region (3500 to 7500 A). These galaxies are part of a sample of 12 early-type galaxies whose infrared colors have been studied (Rembold et al. 2002) in order to detect peculiarities that could evidence merger events. Central stellar velocity dispersion of the galaxies were measured through a cross-correlation method using a kinematic standard star. The central velocity dispersions, together with infrared photometry, allow us to study the behavior of these objects in the Fundamental Plane of elliptical galaxies. We also analyse the central kinematics and its relation to the global kinematics of the galaxies, through the radial velocity and velocity dispersion profiles.
