    Time-resolved Fourier Transform Infrared Emmision Spectroscopy of He2 Produced by a Pulsed Discharge

  • Original language description

    Time-resolved Fourier transform spectroscopy was applied to the study of He-2 infrared emission produced by a pulsed discharge in pure He. In the 1800-8000 cm(-1) region, new electronic bands have been observed in addition to the previously reported transitions. From the observed time profiles of emission spectra, Rydberg states with higher energy than the b(3)Pi state produced efficiently in afterglow plasma have been identified. Rotational assignments and a least-squares analysis for the h(3)Sigma(u)(+)-g(3)Sigma(g)(+) and g(3)Sigma(g)(+)-d(3)Sigma(u)(+) bands in the 3200 cm(-1) region were carried out to determine the molecular constants. A new band from an unidentified g U state to the d(3)Sigma(u)(+) state has been observed in the 6300 cm(-1) region with irregular P- and R-branch intensities.

    Časově rozlišená Fourier transform infračervená emisní spektroskopie He2 produkovaného pulzním výbojem

  • Czech description

    Časově rozlišená Fourier transform spektroskopie byla aplikována při studiu He2 infračervené emise pomocí pulzního výboje v čistém He. V oblasti 1800-8000 cm-1 byly pozorovány nové elektronické pásy. Z pozorovaných časových profilů emisních spekter bylyidentifikovány Rydbergovy stavy s vyšší energií než b3? stav. Byla provedeno rotační přiřazení a analýza pomocí nejmenších čtverců h3.SIGMA.? - g3.SIGMA. a g3.SIGMA.-d3.SIGMA. pásů v oblasti 3200 cm-1. Zároveň byly určeny molekulární parametry. Nový páss nepravidelnou strukturou intensit P a R větví byl identifikován v oblasti 6300 cm-1.
