  • Optical absorption bands at ~18772 and ~18807 cm-1, previously assigned to A2Δ-X2Π electronic origin band transitions of the linear carbon-chain radicals C5H and C5D, respec-tively, have been reinvestigated. The spectra have been recorded in direct absorption apply-ing cavity ring-down spectroscopy to a supersonically expanding acetylene/helium plasma. The improved spectra allow deducing a l-C5H upper state spin-orbit coupling constant A'=-0.7(3) cm-1 and a A2Δ lifetime of 1.6±0.3 ps.
