Abstract

The rotational spectrum of HCN has been measured between 270 and 520 GHz in a cryogenic ion trap instrument employing a double resonance vibrational-rotational scheme based on leak-out spectroscopy. A total of four transitions with quantum numbers ranging from ″ = 2.5 to 5.5 have been observed for the lowest-energy spin-orbit state Π of this open-shell cation, which has an inverted Π electronic ground state. The transitions show well-resolved -doubling components each displaying complex hyperfine splittings due to the presence of two nuclei with non-zero spins, H = 1/2 and N = 1. The accurate transition frequencies and ground state spectroscopic parameters determined for HCN in this work will enable radio astronomical searches of this important cation in the interstellar medium.
