[gmx-users] Does GMX compute coulomb interaction between oxygen and hydrogen in SPC water model?

2009-10-23 Thread xuji
Hi all gromcas users:

In SPC water model, it only has oxygen-oxygen VDW interactons. 
So is it the same with coulomb interatctions?

Thanks for any advice in advance!

No, otherwise it would be a one-point water model. All SPC water atoms
have partial charges - see spc.itp.
