Terahertz spectroscopy and global analysis of the rotational spectrum of doubly deuterated amidogen radical ND_2_. (2017)

Keywords : astrochemistry; ISM molecules; methods: laboratory: molecular; molecular data; techniques: spectroscopic

Abstract:The deuteration mechanism of molecules in the interstellar medium is still being debated. Observations of deuterium-bearing species in several astronomical sources represent a powerful tool to improve our understanding of the interstellar chemistry. The doubly deuterated form of the astrophysically interesting amidogen radical could be a target of detection in space. In this work, the rotational spectrum of the ND_2_ radical in its ground vibrational and electronic X^2^B_1_ state has been investigated between 588 and 1131GHz using a frequency modulation millimeter/submillimeter-wave spectrometer. The ND_2_ molecule has been produced in a free-space glass absorption cell by discharging a mixture of ND_3_ and Ar. Sixty-four new transition ...(more)
