摘要: Vacuum ultraviolet pulsed-field ionization-photoelectron (PFI-PE) spectra of H2S have been recorded at PFI-PE resolutions 0.6–1.0 meV in the energy range 10–17 eV using high-resolution synchrotron radiation. The spectrum, which covers formation valence electronic states H2S+ (X 2B1, A 2A1, and B 2B2), is compared to recent He I photoelectron obtained by Baltzer et al. [Chem. Phys. 195, 403 (1995)]. In addition overwhelmingly dominated origin vibrational band, spectrum for H2S+(X 2B1) found exhibit weak progressions due excitation combination bands ν1+ symmetric stretching ν2+ bending modes. While ionization (IE) here accord with values determined previously laser measurements, observation a new band 12.642±0.001 eV suggests that IE H2S+(A 2A1) may be 0.12 lower than reported study. simula...
