Professor Stanley C. Nyburg's homepage at Department of Chemistry, Kings College, London.

For why phases are important in crystallography, refer to:

Scanned image of the Physical Meaning of the Phase angle alpha(hkl) in Crystallography within "X-Ray Analysis of Organic Structures", by Stanley C. Nyburg, pages 98-99, 1961, Academic Press. This was the first crystallographic text book with such a graphical explanation using such a diagram.


Also: Use of equalities and inequalities in the Determination of Phases alpha(hkl)
