Diffraction Lecture 20: Reflection Conditions

In this lecture we see that for most space groups certain classes of diffraction peaks are systematically absent. Those peaks that are allowed are are said to follow specific reflection conditions. For example in a body centered space group only the reflection indices (hkl) where h + k + l is an even number are seen. We can use this information to dramatically narrow down the choice of space group.
