Subject: D-tryptophan

I am performing gas phase calculations on small peptides.
I want to make a new residue for an 'in-chain' D isomer of tryptophan. I am
familiar with using the RESP procedure to generate charges for new residues,
but do I need to do that here, or can I just swap the charges? Additionally
should I also create new parameters?
Any help with this will be gratefully received.
