We present high-resolution, near-infrared data from the T Tauri star DR Tauri, obtained on 16 February-18 February 2011 using NIRSPEC at the Keck II telescope. Understanding the hydration of protoplanets requires the study of planet-forming disks with particular interest given to the distribution of material, specifically H2O and OH. To find the distribution of H2O and OH in the inner disk material around DR Tauri, the region of the spectrum where H2O and OH emission occurs was sampled. The most robust method for constraining where H2O and OH are located in protoplanetary disks is the technique of spectro-astrometry. The spectra and features were analyzed using spectro-astrometry and the spectro-astrometric signal is then used to determine the spatial extent of emission.
