Hyphenation for 'intermolecular'

Showing how to split the syllables of 'intermolecular'.

Syllabification or syllabication is the separation of a word into syllables, whether spoken or written. The written separation is usually marked by a hyphen when using English orthography (e.g., syl-la-ble) and with a period when transcribing in the International Phonetic Alphabet (IPA). For presentation purposes, typographers may use an interpunct, or a special-purpose "hyphenation point".

At the end of a line, a word is separated in writing into parts conventionally called "syllables" if it does not fit and if moving it to the next line would make the first line much shorter than the others. This can be a particular problem with very long words. Word processing has automated the process of justification, making syllabification of shorter words often superfluous.

An intermolecular force (IMF; also secondary force) is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighbouring particles (e.g. atoms or ions). 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 first reference to the nature of microscopic forces is found in Alexis Clairaut's work Théorie de la figure de la Terre, published in Paris in 1743. Other scientists who have contributed to the investigation of microscopic forces include: Laplace, Gauss, Maxwell, Boltzmann and Pauling. Attractive intermolecular forces are categorized into the following types:Hydrogen bonding Ion–dipole forces and ion–induced dipole force Cation–π, σ–π and π–π bonding Van der Waals forces – Keesom force, Debye force, and London dispersion force Cation–cation bonding Salt bridge (protein and supramolecular) Information on intermolecular forces is obtained by macroscopic measurements of properties like viscosity, pressure, volume, temperature (PVT) data. The link to microscopic aspects is given by virial coefficients and intermolecular pair potentials, such as the Mie potential, Buckingham potential or Lennard-Jones potential. In the broadest sense, it can be understood as such interactions between any particles (molecules, atoms, ions and molecular ions) in which the formation of chemical (that is, ionic, covalent or metallic) bonds does not occur. In other words, these interactions are significantly weaker than covalent ones and do not lead to a significant restructuring of the electronic structure of the interacting particles. (This is only partially true. For example, all enzymatic and catalytic reactions begin with a weak intermolecular interaction between a substrate and an enzyme or a molecule with a catalyst, but several such weak interactions with the required spatial configuration of the active center of the enzyme lead to significant restructuring changes the energy state of molecules or substrate, which ultimately leads to the breaking of some and the formation of other covalent chemical bonds. Strictly speaking, all enzymatic reactions begin with intermolecular interactions between the substrate and the enzyme, therefore the importance of these interactions is especially great in biochemistry and molecular biology, and is the basis of enzymology).
