We present orbital parameters for six double-lined spectroscopic binaries ({iota} Pegasi, {omega} Draconis, 12 Booetis, V1143 Cygni, {beta} Aurigae, and Mizar A) and two double-lined triple star systems ({kappa} Pegasi and {eta} Virginis). The orbital fits are based upon high-precision radial velocity (RV) observations made with a dispersed Fourier Transform Spectrograph, or dFTS, a new instrument that combines interferometric and dispersive elements. For some of the double-lined binaries with known inclination angles, the quality of our RV data permits us to determine the masses M{sub 1} and M{sub 2} of the stellar components with relative errors as small as 0.2%.
