The amplitudes of the resulting oscillations have a strong s-dependence and are typically rescaled by multiplying with s and dividing by the atomic scattering intensity to yield sM(s). A sinusoidal transformation of the interference yielding an atomic pair distribution function (PDF(r)) is shown in Fig. . The PDF shows two maxima at 1.4 Å and 2.4 Å, which can be assigned to three sets of carbon-carbon distances in the molecule. It is convenient to think of these sets of distances, which are marked by color-coded arrows and additionally shown in a depiction of CHD in Fig. , in terms of carbon coordination spheres. The first carbon coordination sphere (nearest-neighbors) is comprised of carbon-carbon bond distances (dark yellow in Fig. ), which are responsible for the maximum at 1.4 Å in the PDF of CHD. The second carbon coordination sphere (next-nearestneighbors) consists of distances between carbon atoms which are bound to the same carbon (purple in Fig. ). The third carbon coordination sphere (next-next-nearest neighbors) consists of distances between carbon atoms connected to two ends of a given carbon-carbon bond (brown in Fig. ). The distances in the second and third carbon coordination spheres are similar enough in CHD that they both contribute to the second maximum at 2.4 Å in the PDF. The PDF has a shoulder to larger distances, which is due to contributions from carbon-hydrogen and hydrogen-hydrogen distances. Due to the much smaller electron scattering cross-section of hydrogen compared to carbon, these contributions are substantially weaker in intensity.
