摘要: Rotationally resolved photoelectron spectra of jet-cooled H2O, HDO and D2O have been recorded near the origin photoionising transition following single-photon ionization using complementary techniques mass-analysed threshold-ionization (MATI) pulsed-field-ionization zero-kinetic-energy (PFI-ZEKE) spectroscopy. A gas mixture with Ar was obtained by mixing H2O (l) in a reservoir bubbling through mixture. To unambiguously assign bands to or D2O, PFI-ZEKE were compared MATI H2O. Analysis rotational structure (v+1 = 0, v2+ v+3 0) ← (v1 v2 v3 transitions (010), (020) (100) levels D2O+ first excited level O–D stretching mode HDO+ provided new information on photoionization dynamics water energy D2O+.
