Abstract

The authors have detected the 2Π_1/2 J = 3/2→1/2 transitions of OH at 163.12 and 163.40 μm and obtained upper limits for the 2Π_3/2 J = 3/2→1/2 transitions of CH at 149.09 and 149.39 μm, in observations of the Kleinmann-Low nebula of Orion. All four flux levels lie between 1 and 1.2×10-17W cm-3. Taken together with existing data on molecular hydrogen and CO and recent data on other OH transitions, the results suggest OH emission from postshock regions at temperatures T ≈ 103K and densities n_H2 ≈ 7×106cm-3 and n_OH ≈ 80 cm-3. The OH column density is N_OH ≈ 4×1016cm-2 in the emitting regions.
