Electronic spectra of linear HC $_{5}$ H and cumulene carbene H $_{2}$ C $_{5}$

Abstract

The $1^{3} Σ_{u}^{-} \leftarrow X^{3} Σ_{g}^{-}$ transition of linear HC $_{5}$ H (A) has been observed in a neon matrix and gas phase. The assignment is based on mass-selective experiments, extrapolation of previous results of the longer HC $_{2 n + 1}$ H homologues, and density functional and multi-state CASPT2 theoretical methods. Another band system starting at 303 nm in neon is assigned as the $1^{1} A_{1} \leftarrow X^{1} A_{1}$ transition of the cumulene carbene pentatetraenylidene H $_{2}$ C $_{5}$ (B).
