[Chimera-users] electrostatic interactions

[Elaine Meng]

Hi Ruchika,
H-bonds include salt bridge interactions.  That is, many H-bonds are salt bridges, and biomolecular (e.g. protein-protein) salt bridges are generally H-bonds.   See the FindHBonds page for a description of what atom types it considers:
