Title: Confirmation of Young Brown Dwarfs in Nearby Moving Groups

Abstract: We propose to observe seven red L dwarfs with NIRSPEC in high resolution mode to obtain radial velocities, gravity measurements, and v \sin i rotational velocities. These observations are necessary to complete our kinematic analysis of 38 young brown dwarf members of nearby moving groups, all less than 150 Myr old. This project will yield a four-fold increase in the number of brown dwarfs with empirically derived ages, and allow us to test brown dwarf evolutionary models.
