Description
| - Na studium reaktivity stavově vybraných atomárních ionů N+ a O+ byla použita disociativní fotoionizace N2 a O2 pomocí synchrotronního záření v koincidenci s fotoelektrony. Přesný výběr jejich základních stavů N+(3P), O+(4S) nebo excitovaných stavů N+(1D), O+(2D), O+(2P) byl dosáhnutý volbou energie fotonů a následnou diskriminací atomárních iontů s kinetickou energií. Obě studované reakce 15N+ + CD4 a O+ + 13CO2 mají důležitou úlohu v chemických procesech v ionosférách Titánu, Marsu a Venuše a jsou silně závislé na excitaci mateřských iontů. Reakce N+ s metanem vedoucí k produktům DCN+ a DCND+, které pocházejí z rozpadu dlouho žijícího komplexu překvapivě není silně závislá na exitaci N+.Oproti tomu disociativní přenos náboje vedoucí k CD3+ je dominantní pro reakci s N+ v základním stavu a nedisociativní přenos náboje vedoucí k CD4+ převažuje v případě, kdy N+ je v excitovaném 1D stavu. Tento neočakávaný výsledek může být vysvětlitelný pomocí spin-orbitových výběrových pravidel ... (cs)
- The dissociative photoionization of N-2 and O-2 by synchrotron radiation in coincidence with threshold photoelectrons is used to produce state-selected N+ and O+ atomic ions to study their reactivity. A pure selection of their ground state, N+(P-3) and O+(S-4), or excited states, N+(D-1), O+(D-2), and O+(P-2), is obtained by the choice of the photon energy and by further discrimination of atomic ions produced with translational recoil energy. Both reactions studied, N-15(+) + CD4 and O+ + (CO2)-C-13, are of major importance for the chemistry of Titan, Mars, and Venus´ionospheres and are strongly affected by excitation of the parent atomic ion. For the reaction of N+ with methane, DCN+ and DCND+ products coming from the decomposition of a long-lived complex are surprisingly not much sensitive to the N+ excitation, whereas the branching ratio between the dissociative charge-transfer channel, leading to CD3+, which is the main product for the ground-state reaction.
