An abundance analysis of the single-lined spectroscopic binaries with barium stars-like orbital elements II. The spectroscopic data

High-resolution spectroscopic observations are presented for 19 single-line d binaries (giants and dwarfs) with orbital elements and mass functions sim ilar to those of barium stars, two radial velocity non-variable barium star s, and two standards. All binary systems contain an unseen low-mass compone nt, presumably, a white dwarf. The equivalent widths and oscillator strengt hs are given for all measured spectral lines.
