I am doing some simulation like recrystallizaiton, crystal A-amorphous-crystal B. This crystal B is different from A and experimentally proved that B is more like crystal C. Even though the recrystallizaiton is not obvious. As far as I have done, the bond lengths and radial distribution functions,coordination numbers for amorphous,B and C have no huge differences. The reason for this is because the crystal B and crystal C both have low symmetry. So my question is how to compare the amorphous, recrystallzed crystal B and the already known crystal C. Thanks a lot..
