Laboratory experiments on the radiation astrochemistry of water ice phases [PDF]
European Physical Journal D : Atomic, Molecular and Optical Physics, 2022 Water (H2O) ice is a ubiquitous component of the universe, having been detected in a variety of interstellar and Solar System environments where radiation plays an important role in its physico-chemical transformations.

Gas-phase Ortho-to-para Ratio of Formaldehyde Formed at Low Temperatures in Laboratory Ices
The Astrophysical Journal Letters, 2023 The ortho-to-para ratio (OPR) of formaldehyde (H _2 CO) has been used as a probe to estimate the formation temperature of molecules in interstellar, circumstellar, and cometary environments, relying on the assumption that nuclear spin conversion is ...

Spiers Memorial Lecture: Astrochemistry at high resolution
Faraday discussions, 2023 Astrochemistry is the science that studies the chemistry in the Universe, namely the combination of two fields: astronomy and chemistry. It started about fifty years ago and it has progressed in leaps and bounds, often triggered by the advent of new ...

The astrochemistry of life [PDF]
Astronomy and Geophysics, 2001 There are many unanswered astronomical questions about the chemical basis of life; a meeting held in August this year by the Astrophysical Chemistry Group of the RAS and the Royal Society of Chemistry took as its starting point the understanding of a number of questions, and reviews of progress towards the answers, report Anita Richards and Peter Sarre.
