Intermolecular force - WikipediaIntermolecular and Surface Forces describes the role of various intermolecular and interparticle forces in determining the properties of simple systems such as gases, liquids and solids, with a special focus on more complex colloidal, polymeric and biological systems. The book provides a thorough foundation in theories and concepts of intermolecular forces, allowing researchers and students to recognize which forces are important in any particular system, as well as how to control these forces. This third edition is expanded into three sections and contains five new chapters over the previous edition. Research workers and students in materials science, especially in biomaterials and polymers, and applied physicists working in these fields. Thermodynamic and Statistical Aspects of Intermolecular Forces 2.
Intermolecular forces IMF are the forces which mediate interaction between molecules , including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e. Intermolecular forces are weak relative to intramolecular forces — the forces which hold a molecule together. For example, the covalent bond , involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics. The investigation of intermolecular forces starts from macroscopic observations which indicate the existence and action of forces at a molecular level. These observations include non-ideal-gas thermodynamic behavior reflected by virial coefficients , vapor pressure , viscosity , superficial tension, and absorption data.
