[gmx-users] SO3- force field parameter?

[A. und B. Nick]

Dear All,

I want to run a MD simulation on a box 
containing a small additive molecule 
that exhibits a SO3- group using the OPLSaa
force field. 
Does anyone have experince with SO3-
and can point me to reasonable parameter.
(A found an entry concerning SO3 at the 
beginning of this list, but the guy seems
not to exist anymore.)

Thanks for all suggestions,
Gitta
