Specifically, the Coulomb potential associated with this force.

When secondary interactions, such as coulombic interactions by acidic silanols (silica compounds) or metal impurities in the stationary phase, exist to a large extent, peak shapes of proteins will deteriorate due to their slow kinetics.

Coulombic interactions are the dominant force between the ions, including dipole, hydrogen-bonding and dispersive forces are also important to the interactions between constituents in the ILs (Tokuda et al.
3) The overlap of [pi] orbital wave functions at short range dominates, and coulombic interactions at long range are neglected.
Sun and Stirner (2001) used molecular dynamics to study the compression of 2-D polystyrene particles at an oil-water interface through monopole-monopole Coulombic interactions.
