The UMIST database for astrochemistry 1995

, 1996
We report the release of a new version of the UMIST database for astrochemistry. The database contains the rate coefficients of 3864 gas-phase reactions important in interstellar and circumstellar chemistry and involves 395 species and 12 elements.

Astrochemistry in an Ion Storage Ring

, 2012
Storage ring studies of low energy electron collisions with molecular ions have been carried out for dissociative recombination (DR) of fluorine-bearing molecules. Here we report on work aiming to improve the understanding of astrochemistry involving HF,

Metal-ion mediated photolytic regulation of diphenylalanine stability: Implications for prebiotic chemical evolution

iScience
Summary: Early Earth’s UV-rich environment, together with abundant transition metals, likely shaped the stability of biomolecules. We investigated how cations influence the UV (254 nm) stability of diphenylalanine (FF).

Astrochemistry: an unfinished symphony

, 2009
Alex Dalgarno has introduced many of the themes that define current research in astrochemistry. Variations on these themes will continue to be played out well into the future. Clear and unambiguous tests of theories of formation of interstellar molecules

Infrared Spectroscopic and Physical Properties of Methanol Ices—Reconciling the Conflicting Published Band Strengths of an Important Interstellar Solid

The Astrophysical Journal
Infrared spectroscopic observations have established the presence of solid methanol (CH _3 OH) in the interstellar medium and in solar system ices, but the abundance of frozen CH _3 OH cannot be deduced without accurate band strengths, optical constants,

Carbon Dioxide Ices—A Sexagennial Update of Infrared Intensities, Band Shapes, and the Formation and Destruction of Crystalline CO2

The Astrophysical Journal
The infrared (IR) band strengths most often used to quantify laboratory and astronomical spectra of CO _2 ices are now 60 yr old, from a time of slide rules and vacuum-tube technology.

The UMIST database for astrochemistry 1999

, 2000
We report a new version of the UMIST database for astrochemistry. The previous (1995) version has been updated and its format has been revised. The database contains the rate coefficients, temperature ranges and - where available - the temperature ...
