Dear Justin, Thanks for your educational answers.

Ions are particularly > problematic in this regard. I've seen this mentioned in the Manual, but hadn't ever hit GROMACS specific details on how to apply polarization in the input files. The only source I could locate is within the GROMACS package, under the name "sw.itp". It does exclusively implement the so called "water polarization" model -at least I think so. Can you please direct me to a source from which I could learn how to polarize GROMACS? I was'not lucky on the Internet and, indeed, even at the GROMACS site or Manual (neighter application examples nor file format descriptions). I appreciate your help so much.
