Observations of some rotational transitions of NHD by microwave optical double resonance
Journal Article

· Astrophys. J., Lett. Ed.; (United States)
The frequencies of the fine and hyperfine structure components of several electric and magnetic dipole transitions in the ground state of NHD in the range 4--12 GHz have been measured using microwave optical double resonance. The transition 1/sub 10/-1/sub 11/ near 73 GHz has also been detected. The latter transition in particular has important implications for the detection of NHD in the interstellar gas clouds.
