Scientific paper

937 radial velocities are listed from coude spectra of 160 visual multiples with known visual orbital elements; these, plus the velocities in paper of Roemer and Sanwal (1980), are discussed. Among the results are (1) systems yielding spectroscopic elements with the visual period, (2) systems probably showing velocity variations during the visual period, (3) systems with short spectroscopic periods, some in addition to detectable motion during the visual period, (4) systems showing no variation in radial velocity during the visual period, either because the components are similar in brightness or the periods are very long, (5) systems with spectral lines too broad to allow the detection of orbital motion, and (6) systems with insufficient data for any conclusions to be drawn at present.
