摘要: Unresolved electronic origin band transitions have been measured for the even-numbered linear carbon-chain radicals (13)C2nH/D with . Spectra of fully 13C substituted 13C8H/D and 13C10H/D isotopologues are presented first time. 12C10H/D 12C12H/D spectra improved signal-to-noise ratio to realise a systematic study profiles. Despite fact that individual rotational cannot be resolved, it is possible derive effective values upper state lifetime. The obtained natural lifetime line broadening parameters 0.8 ± 0.1 cm−1 n = 4, 4.0 0.5 5 4.8 6 indicate internal conversion processes occur in these molecules.
