I start to get a little confused with the discussion of the powder spectrum, but I think I’ve justified all the statements to myself.

Then the orientations start to get confusing on page 8. It reminds me of our discussion of the orientations of nuclear ensembles, but seems to be different.

Smaller things that confused me earlier on were the statement that spin-orbit coupling “admixes small amounts of orbital angular momentum to the ground state”. Maybe it’s talking about the fine-level energy splitting due to spin-orbit coupling that splits the “ground state”?

And I didn’t know what a ligand was, but I looked it up.
