Observations of rotational transitions of CH3OH and NH2 near 1.2 mm.

Sixteen new methanol lines have been detected at frequencies near 242 GHz towards the direction of OMC-1. They correspond to the J = 5 - 4, sk = 0 transitions in the A and E stack of CH3OH. Also towards OMC-1 a broad emission feature was observed, coinciding in frequency with J = 7/2 - 5/2 components of the 3(13) - 2(20) rotational transition of NH2. The observed antenna temperatures of the methanol lines can be reproduced with a thermal excitation model using one temperature, 90 K, and a column density of N(CH3OH) = 5 x 10 to the 16th per sq cm, assuming a 30 inch diameter methanol source.
