Cassini discovered a plethora of neutral and ionized molecules in Titan’s ionosphere including, surprisingly, anions and negatively charged molecules extending up to 13,800 u q−1. In this Letter, we forward model the Cassini electron spectrometer response function to this unexpected ionospheric component to achieve an increased mass resolving capability for negatively charged species observed at Titan altitudes of 950–1300 km. We report on detections consistently centered between 25.8 and 26.0…

Observations of Titan's ionospheric chemistry indicate that molecular growth starts in the upper atmosphere rather than at lower altitude, and that Benzene (C6H6) is created by ion chemistry at high altitudes and its main photolysis product, the phenyl radical, is at the origin of the formation of aromatic species at higher altitude.

Reactions of Azine Anions with Nitrogen and Oxygen Atoms: Implications for Titan's Upper Atmosphere and Interstellar Chemistry.

The rich gas-phase chemistry observed in this work provides a better understanding of ion-atom reactions and their contributions to ionospheric chemistry as well as the chemical processing that occurs in the boundary layers between diffuse and dense interstellar clouds.


Results are presented from a survey for molecular anions in seven nearby Galactic star-forming cores and molecular clouds. The hydrocarbon anion C6H− is detected in all seven target sources,

In insight into the rich gas-phase chemistry of aromatic ion-atom reactions and their relevance to ionospheric and interstellar chemistry, spin conversion is found to be critical for understanding some product distributions.

Negative ions at Titan and Enceladus: recent results.

The detection of heavy negative ions in Titan's ionosphere indicates the existence of heavy hydrocarbon and nitrile molecules in this primitive Earth-like atmosphere, and is indicative of a complex balance between neutrals and positively and negatively charged ions.
