High–resolution spectroscopic observations are presented for 19 single–lined binaries (giants and dwarfs) with orbital elements and mass functions similar to those of barium stars, two radial velocity non–variable barium stars, and two standards. All binary systems contain an unseen low–mass component, presumably, a white dwarf. The equivalent widths and oscillator strengths are given for all measured spectral lines.
Key words: binaries: spectroscopic / stars: chemically peculiar / stars: abundances
