Abstract

We report the first structural characterization of the triplet isomer of C₆. Forty-one rovibrational/fine structure transitions in the v₄(σ_u) antisymmetric stretch fundamental of the C₆ cluster have been measured by diode laser absorption spectroscopy of a supersonic carbon cluster beam. The observed spectrum is characteristic of a centrosymmetric linear triplet state with cumulene-type bonding. The measured ground state rotational constant B₀ = 0·048 479 (10) cm^-1 and the effective bond length r_eff = 1·2868 (1) Å are in good agreement with ab initio predictions for the linear triplet (3Σ_g^-) state of C₆.
