  2. Conjugated system - Wikipedia

    en.wikipedia.org/wiki/Conjugated_system

    Cinnamaldehyde is a naturally-occurring compound that has a conjugated system penta-1,3-diene is a molecule with a conjugated system Diazomethane conjugated pi-system. In theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability.

  3. Conjugate gradient method - Wikipedia

    en.wikipedia.org/wiki/Conjugate_gradient_method

    Conjugate gradient, assuming exact arithmetic, converges in at most n steps, where n is the size of the matrix of the system (here n = 2). In mathematics , the conjugate gradient method is an algorithm for the numerical solution of particular systems of linear equations , namely those whose matrix is positive-semidefinite .

  4. Conjugation - Wikipedia

    en.wikipedia.org/wiki/Conjugation

    Conjugate vaccine, in immunology; Conjugation (biochemistry), covalently linking a biomolecule with another molecule; Conjugate (acid-base theory), a system describing a conjugate acid-base pair; Conjugated system, a system of atoms covalently bonded with alternating single and multiple bonds

  5. Cross-conjugation - Wikipedia

    en.wikipedia.org/wiki/Cross-conjugation

    Whereas a normal conjugated system such as a polyene typically has alternating single and double bonds along consecutive atoms, a cross-conjugated system has an alkene unit bonded to one of the middle atoms of another conjugated chain through a single bond. In classical terms, one of the double-bonds branches off rather than continuing ...

  6. Conjugate variables (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_variables...

    Just as a small increment of energy in a mechanical system is the product of a force times a small displacement, so an increment in the energy of a thermodynamic system can be expressed as the sum of the products of certain generalized "forces" which, when unbalanced, cause certain generalized "displacements" to occur, with their product being the energy transferred as a result.

  8. Hückel's rule - Wikipedia

    en.wikipedia.org/wiki/Hückel's_rule

    The best-known example is benzene (C 6 H 6) with a conjugated system of six π electrons, which equals 4n + 2 for n = 1. The molecule undergoes substitution reactions which preserve the six π electron system rather than addition reactions which would destroy it. The stability of this π electron system is referred to as aromaticity. Still, in ...
