# Introduction¶

This notebook shows how to plot an XRD plot for the two polymorphs of CsCl ($Pm\overline{3}m$ and $Fm\overline{3}m$). You can also use matgenie.py's diffraction command to plot an XRD pattern from a structure file.

# $\alpha$-CsCl ($Pm\overline{3}m$)¶

Let's start with the typical $\alpha$ form of CsCl.

Compare it with the experimental XRD pattern below.

# $\beta$-CsCl ($Fm\overline{3}m$)¶

Let's now look at the $\beta$ (high-temperature) form of CsCl.

Compare it with the experimental XRD pattern below.
