In the regular solution, specific interactions such as hydrogen bonding, acid-base association, and charge transfer do not occur, but the intermolecular forces are no longer equal. That is, the energies associated with A-A and B-B interactions are not equal to the A-B interactions. Under these conditions, if the molecules are about the same size, it can be shown that GE is given by...

Lewis s research was wide-ranging and outstanding. He published important papers on chemical bonds, acid-base theory, and thermodynamics. He also developed firm ideas about howto build a chemistry department. His philosophy of education was something less than egalitarian. Writing in the Journal of Chemical Education, the distinguished chemist Gerald Branch spelled out Lewis s ideas "[F]or a chemist to be useful to... 

Asphaltenes are generally defined as those components in petroleum and coal liquids that under certain conditions are soluble in benzene but insoluble in aliphatic solvents, such as n-pentane, n-heptane, or cyclohexane. This definition obviously includes a broad variety of components, as insolubility in the above solvents can be caused by high molecular weight, high polarity, hydrogen bonding, acid-base complexing, or combinations of these parameters. 

The Gutmaim s Acceptor Number (AN) was proposed [Gutmann, 1978] as a quantitative empirical parameter of solvent hydrogen bond acidity based on P-nmr shifts of thiethylphosphine oxide at infinite dilution, calculated as AN = -6 " 2.349.

Very straightforward effects of surface chemistry of carbons are seen on the adsorption from solutions of aromatics [10-17], dyes [18], heavy metals [19-24], pharmaceuticals [25-27], polar species such as alcohols [28-30], acids or aldehydes [31,32], and even small-molecule gases [33,34]. In those applications the species present on the carbon surface can enhance the specific interactions or even alter the porosity via blocking of pore entrances for molecules to be adsorbed. Specific interactions include hydrogen bonding, acid-base, and complexation.

According to Drago, specific interactions can be described as localized donor-acceptor interactions involving specific orbitals in terms of two parameters, viz. E for electrostatic interactions and C for covalent interactions according to Kamlet and Taft, " such interactions can be described in terms of hydrogen-bonding acid-base interactions. In fact.

The importance of strong specific interactions in polymer adhesion (eg., covalent bonding, acid-base interaction) is well-known. However, these interactions are difficult to study directly, particularly for multifunctional surfaces. Derivatisation techniques have been developed which allow X-ray photoelectron spectroscopy (ESCA) to quantify functional group populations and to assess the success of specific modification techniques. Derivatised surfaces can then be used to study the role of specific interactions.
