I think one may need to distinguish between three different kinds of dehydration experiment, because of the different forces they will exert on a crystal to shrink the unit cell, creating new stabilizing crystal contacts or perhaps causing contacts to fail in a chaotic manner, disordering the cry

Juan, Humidity variation is what vapour diffusion crystallization achieves. In your list of all possible dehydration methods you would end up classifying all vapour diffusion experiments as a case of dehydration. After nucleation, crystals continue to grow and the drop continues to become mor

Dear all, From Leonid's reply earlier you can see a problem some of us have been having for a while now, when looking for literature regarding dehydration. Most of you that perform dehydration either don't consider it happening or don't report it in great detail in your publications. This is on
