The strength of the Ca II triplet in absorption at 8498/8542/8662 A has been found to serve as a good luminosity indicator for metal-rich stellar populations; high S/N near-IR spectroscopic data are presented for the nuclear regions of 42 normal and active galaxies. The normal galaxies' Ca II triplet strengths exhibit a small spread around a mean value of 7 A. The large equivalent width of the IR Ca II triplet in Seyfert nuclei furnishes a unique means for probing the gravitational potential close to the central engine. Nuclear velocity dispersions in 'active' galaxies are comparable to those in normal ones of similar luminosity.
