Interpretation of crystal structure determinations
This note is an
illustration of the basic principles of X-ray crystal and provides an overview
of the successive stages of a crystal structure determination. Topics covered
includes:crystallization, diffraction, structure determination, symmetry,
intramolecular geometry, including thermal motion analysis, graphics, intermolecular geometry, including hydrogen bonding, miscellaneous
subjects, including powder diffraction, graph sets, twinning, absolute
configuration, data bases, validation, -ray crystallography and chemical
bonding.
