We use high-signal-to-noise (between ~ 200-500), high resolution (R ~
45,000) KECK HIRES spectroscopy of 13 candidate post T Tauri stars in
the field to derive basic physical parameters, lithium abundances and
radial velocities.  We utilize qualitative age information determined
from Li abundances, chromospheric emission and kinematic UV plane
positions to distinguish pre and post main sequence objects.  Based on
these criteria and H-R diagram position, we identify 5 probable post T
Tauri stars.  We also examine irregular variability using the
HIPPARCOS photometry annex, and search for the presence of infrared
excesses.
