Thank for your replyThe solvent is not directly involved in the proton transfer process, i mean is neither donor nor acceptor, but just create a barrier by H-bonding that is opposed to the proton transfer reaction. The proton transfer itself is intramolecular.
This problem can be handle by EVB calulations, our results are encouragingbut we would like to have some helping hand.

I think you need to be more specific in your question. Is the protic
solvent directly involved in the proton transfer event? (That is, is there
an intermediate that involves proton transfer to or from a solvent molecule?)
That sort of calculation is not directly supported in Amber, although what is
there might form a useful foundation for code extensions.
If the solvent is "innocent" (just providing a background environment),
then you handle it in the same way as you would for non-EVB calcualtions.
In practice, one should always simulate the starting and ending states
with non-EVB calcualtions first (to make sure you are happy with the
results,) before tackling the transfer problem.
