Abstract:
    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.
