What is it about?
We're looking at subtle details of the crystal structure to understand how molecules connect to each other and how these interactions lead to changes of structure. This is an example of a material that can form in different structures, and we're trying to model the X-ray scattering from the different structures.

Why is it important?
It's important because the information in the diffuse scattering (the broad features that occur throughout the X-ray scattering pattern) are usually ignored, and we believe they can contribute much to our understanding.
Perspectives
This is not one of our major results, to be honest, but I think it shows how our methods have evolved to the point where the work is now more routine and we can quickly see subtle details.
