Radial velocities are determined for 81 members of the Sco-Cen association in order to discover the radial velocity variables. The first orbits are computed for 10 systems, along with improved orbital elements for another seven systems, using published observations in both cases. The axial rotation of the association members is used to test whether both subgroups identified in the association follow the proposed correlation between percentage of binaries and axial rotation. The period distribution is studied using all the information available on binary systems (spectroscopic binaries, visual binaries, and common proper-motion stars). The total observed multiplicity is derived, and a probable significant difference in the total multiplicity is found between the two subgroups. An attempt is made to obtain the true multiplicity using appropriate incompleteness numbers, and some statistical information about the distribution of the secondary masses is derived. Systems with similar masses seem to be favored regardless of orbital period.
