Spectroscopic binaries play an important role in the improvement of pre-main sequence stellar evolution models because they provide precise masses and mass ratios with which to test the theoretical tracks. High-resolution, near-infrared spectra obtained from NIRSPEC on Keck II and PHOENIX on Gemini South for two recently identified young, low-mass, double-lined spectroscopic binary stars, RXJ1622.7-2325Nw and ROXR1 14, were analyzed. These objects lie in the Ophiuchus star forming region. We used two-dimensional cross-correlation of our target spectra with standard stars to measure radial velocities for both components in these systems, and hence determine binary solutions. Over a dozen data points for each target yield accurate orbital elements for both of these short-period, near-unity mass ratio pairs. As only a few dozen pre-main sequence, double-lined spectroscopic binaries are currently known, these well-characterized systems are important for increasing the total sample size.
