[gmx-developers] different nb parameters for inter and intramolecular interactions

hi guys,

sorry to post it here, but i already tried gmx-users with no luck. maybe 
someone who knows the code better might now...

is it possible to have in gromacs 2 sets of nonbonded parameters for the
same atom types?
our potential for water consists of following terms:
coulombic interaction between all particles (including intramolecular)
buckingham potential for O-H intramolecular
buckingham potential for O-H intermolecular

therefore, i've two atom types (O and H) that have different nb 
parameters for intramolecular and intermolecular interactions. can i 
somehow define and use this setup in gromacs? i don't see any solution...

thank you for any advice. best regards,
