Peaks labelled with plane indices.
Also known as: hkl peak labels, Powder reflection labelling
The convention labelling each peak of a powder diffraction pattern with the plane indices of the reflection producing it.
Labels each peak of a powder diffraction pattern with the plane indices of the reflection that produced it.
Contexts: Laboratory
Collapses three dimensions into one, so several distinct reflections may fall at the same position and share one peak, which is why powder indexing is harder than single crystal indexing.
Contexts: Laboratory
A trace of peaks above a baseline, each peak carrying three index figures written beside or above it.
