Diffuse scattering is usually modeled in the Q (reciprocal) space, as discussed in many chapters of this book. However, there is an alternative real-space approach via the atomic pair distribution function (PDF). In this chapter we first discuss how the PDF determined through pulsed neutron diffraction provides knowledge of the local atomic structure and how it seamlessly connects ...
