The solution of a crystal structure consists in combining information about the magnitudes of the |f|2’s (obtained from experimental observation of a diffraction experiment) and some other information about the structure to obtain the positions of the atoms within the crystal unit cell. Other facts about the structure, such as thermal motion etc., may be obtained and with restricted data it is true that atomic resolution may not be achieved, but stripped of all else, this statement expresses the fundamental process of structure determination. The important point is that some extra information however meagre has to be added to the diffraction data.
