Faraday Discussion 133 took place at Abbaye de St Jacut , St Jacut de la Mer, Brittany, France from 24 April 2006 - 26 April 2006. It was only the fourth time that a Discussion has been held outside the UK.
The meeting focussed on recent astronomical observations of molecules in various regions and eras of the Universe, and on describing the processes that determine the chemistry. These processes include gas phase neutral exchanges and ion-molecule reactions, surface reactions on dust grains, and the radiative processing of dirty ices.
