Certain experimental analytic facilities are too large and expensive to be set up by individual research groups or universities and are instead established and supported at national or international level. Among such national facilities, those for synchrotron radiation and neutron scattering are particularly useful for the study of the structure, chemical composition, dynamics and magnetic and electronic properties of materials. This course first outlines the principles of interaction of powerful X-rays with materials and describes how these principles may then be exploited in crystallography and chemical analysis with information on valence states and local chemical environment at sub-micron resolution. Neutrons provide a complementary probe that is particularly sensitive and informative about light elements such as hydrogen, about magnetic structure and about atomic and molecular motion relevant to chemical diffusion and magnetic excitations.

In this third lecture, we study Synchrotrons:

• Tackling the phase problem: multiple isomorphous replacement and multiwavelength anomalous dispersion
• Protein crystallography: principles and examples of applications
• Single crystal diffraction in chemistry and materials science: examples of applications
• Resonant X-ray scattering: principles and examples of applications in materials science and physics
