Web‘Moreover, we used single crystal x-ray diffraction analyses to unambiguously confirm the structure of the nickel species,’ explains Martín. They also carried out DFT calculations to further investigate the interactions between the nickel catalytic complexes and the additives. In fact, it was computational chemistry that unveiled an effect ... WebFor XRD a crystal is defined as perfect 3-D order. This corresponds to the strictest definition of a crystal. For a semi-crystalline polymer, for instance, 100% crystallinity is never obtained by this definition since there are large interfacial regions where some degree of disorder is present.
