Spectroscopic orbits, based on material of higher resolution than employed previously by others, are derived for the H and K emission binaries WW Dra, RZ Eri, MM Her, VV Mon, LX Per, and SZ Psc. For the eight systems, including RS Cvn and Z Her from Paper I (45.117.095), velocities of the hotter components are based on numerous absorption lines in the blue-violet spectrum. Only for the long-period system RZ Eri are reliable velocities obtained for the cooler components from absorption lines in this region, and recourse is had to Ca II emission and to absorption lines in the visual region of the spectrum. Difficulties with velocities from the emission lines and from the Na D absorption lines are discussed.
