Lecture notes
by Dr. Peter Mueller on crystal structure analysis through X-ray diffraction
techniques include key topics like principles of symmetry and space groups,
geometry of diffraction, and computation of structure factors. The lecture goes
on to discuss problems such as the phase problem and direct and Patterson
techniques to solve it. It also encompasses electron density maps and refinement
of structures. Practical issues like growing good-quality crystals and powder
diffraction methods are addressed, besides the limitations of X-ray diffraction.
The notes are a treasure trove of knowledge on the basics of crystallography and
its applications combined with insight into structure databases.
This note covers the
following topics: Structural Dilemma -Isomers, X-Ray results, Crystal lattice
and unit cell, Unit cell choice, The seven crystal systems, Space groups in 3D,
Bragg’s law, Orthorhombic direct and reciprocal cell, Reciprocal lattice, Ewald
sphere, X-Ray diffractometer.
