Hydrocarbon anions in interstellar clouds and circumstellar envelopes

Tom J. Millar, +4 more
- 04 May 2007 - 
TL;DR: The recent detection of the hydrocarbon anion C6H- in the interstellar medium has led to the synthesis of hydrocarbons in a variety of interstellar and circumstellar environments as discussed by the authors, where the anion/neutral abundance ratio can be quite large, on the order of at least a few percent, once the neutral has more than five carbon atoms.

Low-temperature formation of polycyclic aromatic hydrocarbons in Titan’s atmosphere

Long Zhao, +8 more
- 01 Dec 2018 - 
TL;DR: Zhao et al. as discussed by the authors showed that small polycyclic aromatic hydrocarbons (PAHs) can by synthesized by rapid, barrierless reactions in Titan's low-temperature environments.

Carbon chain anions and the growth of complex organic molecules in Titan's ionosphere

R. T. Desai, +22 more
- 26 Jul 2017 - 
TL;DR: In this paper, the mass resolving capability of the Cassini electron spectrometer was improved to achieve an increased mass resolution capability for negatively charged species observed at Titan altitudes of 950-1300 km.

Negative ions at Titan and Enceladus: recent results

Andrew J. Coates, +8 more
TL;DR: The detection of heavy negative ions (up to 13 800 amu) in Titan's ionosphere is one of the tantalizing new results from the Cassini mission as mentioned in this paper, which indicate the existence of heavy hydrocarbon and nitrile molecules in this primitive Earth-like atmosphere.

Time-of-flight mass spectrometer with improved resolution

W. C. Wiley, +1 more
- 01 Dec 1955 - 
TL;DR: In this paper, a new type of ion gun is described which greatly improves the resolution of a nonmagnetic time-of-flight mass spectrometer, and the focusing action of this gun is discussed and analyzed mathematically.

A Production of Amino Acids Under Possible Primitive Earth Conditions

Stanley L. Miller
- 15 May 1953 - 
TL;DR: In this study, an apparatus was built to circulate CHI4, NH3, H2O, and H2 past an electric discharge, and the resulting mixture has been tested for amino acids by paper chromatography.

Current status of transition-state theory

Donald G. Truhlar, +2 more
- 21 Jul 1983 - 
TL;DR: In this article, the authors present an overview of the current status of transition-state theory and its generalizations, including recent improvements in available methodology for calculations on complex systems, including the interface with electronic structure theory, progress in the theory and application of transitionstate theory to condensed-phase reactions, and insight into the relation of transition state theory to accurate quantum dynamics.
