What's the difference between a chiral shift reagent and chiral resolving reagents like Mosher's derivatives?

Are Mosher's derivatives covalently bound?

It's an organic molecule. http://en.wikipedia.org/wiki/Chiral_derivatizing_agent [nofollow]

The reaction with Mosher's reagent forms a covalent bond. The reaction with the shift reagent only forms a coordination compound.
