Jeremy’s research revolves around using various techniques (NMR, crystallography and DFT calculations) to provide information about exactly where hydrogen atoms are located in crystal structures, and exploring the merits and shortcomings of the various techniques for this purpose. When he isn’t trying to persuade a supercomputer to calculate what he wants, he enjoys playing the trumpet with the Oxford University Big Band, plays squash and designs prize-winning posters.

Jeremy Law, a Part II student working with Dr Nick Rees and Dr David Watkin, has won a prize for his poster entitled “Alternative Approaches to Hydrogen Atom Location in the Solid State”. He presented his work to the joint ISIS Crystallography User Group and British Crystallographic Association PCG/SCMP meeting “Current Research in Physical Crystallography”

Because they scatter X-rays weakly, H atoms are often abused or neglected during structure refinement. The reasons why the H atoms should be included in the refinement and some of the consequences of mistreatment are discussed along with selected real examples demonstrating some of the features for hydrogen treatment that can be found in the software suite CRYSTALS.

The final dinner of the British Crystallographic Association Spring Meeting in Warwick was interrupted, as always, with the prize winning awards. Amber Thompson was awarded the International Union of Crystallography Prize (a copy of International Tables) for her explanation of the advantages of choosing non-standard space groups. Kirsten Christensen was awarded the Durward Cruickshank prize for a young crystallographer who had made an outstanding contribution to crystallography.
