We propose to conduct a pathfinding survey of H2 emission from young stars with disks. We will observe 25 sources covering a range of age, mass, inclination, and environment in the S(1) and S(2) mid-IR rotational lines using TEXES on Gemini. With 1 hour of observing time, we will reach line flux sensitivities comparable to the capabilities of Spitzer because of the high spectral resolution of TEXES and large aperture of Gemini. For detected sources, we will also observe the S(4) line. Line ratios are sensitive to warm (200 K < T < 800 K) gas and provide temperature and mass estimates. Where practical, we will use line profile measurements to relate mass and temperature to disk radius using Keplerian rotation. Knowledge of these currently poorly-constrained physical parameters is important to issues of disk chemistry and planetary formation.
