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.
Conjugation is the variation in the endings of verbs (inflections) depending on the person (I, you, we, etc), tense (present, future, etc.) and mood (indicative, imperative, subjunctive, etc.). Most French verbs are regular and their inflections can be entirely determined by their infinitive form.
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; Conjugate variables (thermodynamics), pairs of variables that always change ...
In organic chemistry, homoconjugation is a type of conjugated system where two π-systems are separated by one non-conjugating group. See Conjugated system#Mechanism . Topics referred to by the same term
If these groups are in direct conjugation with the pi-system of the chromophore, they may increase the wavelength at which the light is absorbed and as a result intensify the absorption. A feature of these auxochromes is the presence of at least one lone pair of electrons which can be viewed as extending the conjugated system by resonance.
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 ...
Aside from être and avoir (considered categories unto themselves), French verbs are traditionally [1] grouped into three conjugation classes (groupes): . The first conjugation class consists of all verbs with infinitives ending in -er, except for the irregular verb aller and (by some accounts) the irregular verbs envoyer and renvoyer; [2] the verbs in this conjugation, which together ...
In mathematics, two functions are said to be topologically conjugate if there exists a homeomorphism that will conjugate the one into the other. Topological conjugacy, and related-but-distinct § Topological equivalence of flows, are important in the study of iterated functions and more generally dynamical systems, since, if the dynamics of one iterative function can be determined, then that ...
