Resumen:
We present near-infrared spectra for red giants of L11, NGC 339 and K28, three old or intermediate-age star clusters of the Small Magellanic Cloud (SMC). The spectra were obtained with the Very Large Telescope (Cerro Paranal, Chile), with a dispersion of 0.85Å/pixel covering 1600Å in the CaII triplet region. We derive mean cluster metallicities and radial velocities with typical errors of 0.12 and 2.5 km/s, respectively. The obtained results, together with others previously reported by our group, provide relevant information to improve the global knowledge of the SMC chemical properties.
