We used OH 18 cm observations from the GBT and the E(B-V) map from Schegel, Finkbeiner, & Davis (1998) to obtain the molecular mass of the envelope of the translucent molecular cloud, MBM40. We detected OH emission in regions with E(B-V) as low as 0.12 magnitudes and determined from the dust maps that the molecular mass in the envelope of the cloud is approximately 10 solar masses. This is comparable to the mass along the previously-mapped dense regions of the cloud (E(B-V) > 0.2 magnitudes). The OH 18 cm lines are an excellent tracer of the low-density, low-extinction regions in translucent molecular clouds. A portion of this research was supported by an NRAO Student Observing Support Award.
