Dummy atoms in free energy calculation

Dear AMBER community,
I'd like to ask about what rules there are for choosing the parameters for
dummy atoms. Specifically, I have an H1 atom and a dummy "attached" to it.
This will be "mutated" into OH - HO. For the dummy, should I use both the
bond parameters as in OH-HO or just the equilibrium value or totally
different? What then? What about other parameters?

Or could yopu point me to some literature where this problem is dealt with?

Thank you in advance,

   Martin
