N2 - The pure rotational spectrum of LiCCH (X̃ 1Σ) in its ground and v5 vibrational states has been recorded using direct absorption, millimeter/sub-millimeter spectroscopy in the range of 105-538 GHz. For the main isotopomer, 21 transitions were measured for the ground state and 10 transitions each for the excited levels v5=1, 2, and 3, where ℓ-type doubling was resolved. Several transitions were also recorded for 6LiCCH, Li13CCH, LiC13CH, and LiCCD. All were observed in their natural abundances except for LiCCD. Rotational, ℓ-type doubling and vibration-rotation constants were determined for LiCCH, as well as rs and ro structures.
