Abstract
Radial velocities of 76 objects in the direction of the galactic centr e based on 153 spectra (range 3500 - 7350 Angstrom) are presented. Usi ng the dispersion 45 - 100 Angstrom/mm the internal error of the mean object is 12 km/s depending on the number of lines used, whereas the e xternal error was derived to be +/-4.7 km/s. The excitation classes of the nebulae were also estimated.
