We present the results of absorption spectroscopy on the inner region of 34
Sa-Sc galaxies. We have determined the central velocity dispersion and, fo
r 32 of these objects, stellar rotation curves and velocity-dispersion prof
iles. Some of these profiles are limited to the bulge, some others do reach
a region dominated by the luminosity of the disk. These data are intended
to provide basic material for the study of the mass distribution and dynami
cal status in the central regions of spiral galaxies. Although no elaborate
bulge-and-disk photometric decomposition is performed, we estimate the eff
ects of limited resolution and contamination by disk light on the central v
elocity dispersion of the bulge.
