Bonding Mechanisms
Van der Waals – essentially electrostatic attraction from temporary dipoles and are a very weak interaction. They are at their greatest relative contribution in the nonpolar phases like the dimethylsiloxanes.

Hydrogen bonding results from the attraction of positive and negative charges of hydrogen and non-bonding pairs of electrons and is the force that holds water molecules together as liquid.

The p-bonding is associated with the aromatic class of compounds that include benzene rings. Molecules with these loose clouds of donut shaped electronic charges have their own attraction towards each other. The p-bond in benzene is perpendicular to the benzene ring bonds so they interact more easily if the shape of the molecules does not create steric hindrance.

Stationary phases consist of basic polymer units with functionalities that can be modified by the addition of various moieties during synthesis. These moieties can be added in various amounts to create different concentrations of a particular functionality.
