Electronic spectra of linear HC${}_5$H and cumulene carbene H${}_2$C${}_5$

M. Steglich, J. Fulara, S. Maity +2

The $1^3{\Sigma }_u^{-}\leftarrow X^3{\Sigma }_g^{-}$ 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, extrap…
