Symbolic Addition,1991; Schenk and Kiers, 1983; Overbeek and Schenk, 1978; Schenk, 1971). For an Advanced Study Instute there is one more advantage: the procedures used in Symbolic Addition enable easy insight in the actual processes going on in Direct Methods and as a result it is of great educational value too.

Quartets and Other Phase Relationships,nts and those, for which it is possible to estimate phase sums. Of course, for direct methods the latter are the only important invariants, because reliable phase relationships are the basis of all existing phasing methods, whereas for any structure there are millions more of useless structure invariants.

Patterson Methods,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.

Mayank Jyotsna Soni,Soumya Sarkar atoms) and since many more intensities can be measured, relationships among the structure factors F., and thus among the phases ., must exist. Direct Methods identify and use these phase relationships to solve the phase problem.

Sports Performance and the Brain in greater detail, could restrict general phases in the non-centrosymmetric case and Sayre’s equation (Sayre, 1952) could be applied to any equal-atom structure regardless of space group and therefore could put some constraints on the phases of the involved structure factors.
