hi,folks

In amber 8, Gnp = SURFTEN * SASA + SURFOFF.

In amber9 , a new nonpolar solvation model with an explicit treatment of dispersion interaction was included .
 Gnp = G(disp) + G(cavity) .

In Gaussian03, Gnp = G(Cavitation) + G (Dispersion) + G (Repulsion)

In amber9, the dispersion interaction and cavatitation energy were treated explicitly .
 But where is the repulsion energy, was it compressed into the cavatitation energy against experiment ?





  Many thanks !
