Thermal expansion and structure solution

rowlesmr

I seem to recall reading (about) a paper that was about using thermal expansion as a tool to help with structure solution/indexing by being able to differentiate impurity peaks and slight differences in a/b/c/beta as they'd change differently with temperature.

Does anyone know what I'm talking about, or am I just imagining it?

Thanks

Matthew, there's a Shankland and David paper. I don't have the ref at the breakfast table but it should be easy to find.

That's the one!
