Laboratory rotational spectrum of CN in the 1 THz region.
Abstract
The rotational absorption spectrum of the cyanide radical, CN, in its X^2Sigma^+^ ground electronic state has been measured in the frequency region between 560 and 1020GHz. The radical was produced in a DC discharge of methyl cyanide, CH_3_CN, and molecular nitrogen, N2. The measured lines should be of use to radio astronomers searching for CN in high excitation regions of the interstellar medium.
