Hi Lachele,
I simulated in the past the galactose and it looks good to me. I need to simulate sugar derivatives that have the galactose moiety bound to a substitute indole ring, one of the molecule is X-gal.
So I would like to get the parameters for the indole portion and use the standard parameters for the galactose moiety. Does this make sense? Or shall I just calculate the ESP with Gaussian of the X-gal?
Thanks,
Paola

Yes... what Dave said. I didn't see that before sending my response. But,
that's the basic procedure: let's make sure you know how the existing stuff
works first.
