For more than 100 years, X-ray diffraction has been used to determine molecular structure. Nowadays, small molecules can be studied routinely, and even gigantic structures like those of ribosomes can be determined. However, it is necessary to work with powders or crystals, which is an unnatural environment compared to the solution phase where most chemistry happens.
We have developed the use of synchrotron x-ray, and advanced neutron sources for studying molecular structure in real reaction mixtures. The student will synthesize metal cluster structures of varying sizes, flexibilities and oxidation states, and perform scattering experiments at major European and international facilities. She/he will use advanced modelling techniques to solve and refine the structures of transient intermediates in catalysis, ‘uncrystallizable’ reduced phases and observe host-guest interactions. These experiments will therefore determine the scope and limits for ‘chemistry beyond the crystal’.
Depending upon the interests of the student, the project can then expect to develop in the direction of self-assembly/cluster growth, or more advanced modelling like molecular dynamics simulations. The former would involve e.g. mass spectrometry, microscopy etc, while the latter direction would focus on possible solvent interactions using neutron scattering.

9 Av. Alain Savary, BP 47870, F-21078 DIJON Cedex, France
Contract duration: 36 months
Application deadline: September 15th 2018
Starting Job: From 1st October 2018
The candidate should hold a master’s degree or engineer school diploma in chemistry with honours. He/she would ideally have experience of characterization using x-ray diffraction/total scattering methods. A background in polyoxometalate/cluster chemistry and expertise in e.g. spectroscopy and electrochemistry would also be appreciated. The student should also have an interest in learning basic programming skills in e.g. Igor Pro/Matlab/Python etc. This will be essential for the success of the project, which will involve a mixture of experimental and modelling work at (inter)national laboratories. A good knowledge of English and/or French is also required.
