We have obtained high-resolution 2-μm spectra of six late-type stars within 2 pc of the Galactic Center. We have derived spectral types, reddenings, and radial velocities for these stars. We find the supergiant density in the Galactic Center is lower than in previous determinations. No correspondence is found between stellar velocities and Ne II velocities observed along the same line of sight. No systematic rotation or ordered motion is seen in the stellar velocity distribution. The mass distribution derived from the stellar velocities is compared to those derived from gas velocities and from the 2-μm light.
