Laboratory measurements of millimeter and submillimeter rotational transitions of NH2

Abstract

The frequencies of the 3<SUB>13-2</SUB> sub 20 and 1<SUB>10-1</SUB> sub 01 rotational transitions of NH2 have been measured by means of millimeter and submillimeter microwave spectroscopy. The fine and hyperfine components of the former lie near 240 GHz and the latter near 465 GHz. These transitions appear to be the most favorable for the detection of the important NH2 radical in dense interstellar clouds.
