Welcome to the Parsons Group Website. Within these pages you will find information on our members, our research, contact information and some of the more recent publications from the group.
We are one of a very few groups in the world to be engaged in the study of the effect of pressures of 1000s of atm on the structures of molecular compounds. We are currently focusing on organic and magnetic systems, while also investigating whether pressure can be used to fine-tune metal extraction processes. This pioneering step in Gigapascal Chemistry hopes to make metal extraction more selective and more environmentally friendly. We are part of The Centre for Science at Extreme Conditions (CSEC), a World-leading centre of excellence for extreme conditions science, equipped with state-of-the-art diffraction, computing, magnetism and spectroscopy facilities.
The figure below shows a typical Merrill-Bassett Diamond Anvil Cell (DAC) used to exert high pressure onto molecular samples. High pressure can be used as a direct probe of structure-property relationships, particularly in coordination compounds, where properties including magnetism and colour are intimately dependant on pressure-sensitive structural features such as metal-ligand bond distances and angles.
