Astrochemistry is the study of the abundance and reactions of molecules in the universe, and their interaction with radiation. [1] The discipline is an overlap of astronomy and chemistry . The word "astrochemistry" may be applied to both the Solar System and the interstellar medium .
The discipline of astrochemistry includes understanding how these molecules form and explaining their abundances. The extremely low density of the interstellar medium is not conducive to the formation of molecules, making conventional gas-phase reactions between neutral species (atoms or molecules) inefficient.
Professor Williams field of study is astrochemistry, involving the study of molecular line emissions in outer space to analyse and interpret the evolutionary process of the universe. He led research groups at both Manchester and London and produced more than 300 publications in journals and books.
Meteorites are often studied as part of cosmochemistry. Cosmochemistry (from Ancient Greek κόσμος (kósmos) 'universe' and χημεία (khēmeía) 'chemistry') or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions. [1]
