  2. Acetylferrocene - Wikipedia

    en.wikipedia.org/wiki/Acetylferrocene

    Acetylferrocene is the organoiron compound with the formula (C 5 H 5)Fe(C 5 H 4 COCH 3). It consists of ferrocene substituted by an acetyl group on one of the cyclopentadienyl rings. It is an orange, air-stable solid that is soluble in organic solvents.

  3. Electro–optic effect - Wikipedia

    en.wikipedia.org/wiki/Electro–optic_effect

    Kerr effect (or quadratic electro-optic effect, QEO effect): change in the refractive index proportional to the square of the electric field. All materials display the Kerr effect, with varying magnitudes, but it is generally much weaker than the Pockels effect; electro-gyration: change in the optical activity. Electron-refractive effect or EIPM

  4. Electronic effect - Wikipedia

    en.wikipedia.org/wiki/Electronic_effect

    In organic chemistry, the term stereoelectronic effect is also used to emphasize the relation between the electronic structure and the geometry (stereochemistry) of a molecule. The term polar effect is sometimes used to refer to electronic effects, but also may have the more narrow definition of effects resulting from non-conjugated ...

  5. Ferrocene - Wikipedia

    en.wikipedia.org/wiki/Ferrocene

    Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2.The molecule is a complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents.

  6. Polarizable continuum model - Wikipedia

    en.wikipedia.org/wiki/Polarizable_continuum_model

    The polarizable continuum model (PCM) is a commonly used method in computational chemistry to model solvation effects. If it is necessary to consider each solvent molecule as a separate molecule, the computational cost of modeling a solvent-mediated chemical reaction would grow prohibitively high.

  7. Ethylferrocene - Wikipedia

    en.wikipedia.org/wiki/Ethylferrocene

    It is a derivative of ferrocene containing an ethyl group on one of the two cyclopentadienyl rings. Relative to the properties of ferrocene, its melting point is lower and its solubility of the compound in hydrocarbon solvents is improved.

  8. Hydrophobic-polar protein folding model - Wikipedia

    en.wikipedia.org/wiki/Hydrophobic-polar_protein...

    The hydrophobic-polar protein folding model is a highly simplified model for examining protein folds in space. First proposed by Ken Dill in 1985, it is the most known type of lattice protein: it stems from the observation that hydrophobic interactions between amino acid residues are the driving force for proteins folding into their native state. [1]

  9. Hapticity - Wikipedia

    en.wikipedia.org/wiki/Hapticity

    Ferrocene contains two η 5-cyclopentadienyl ligands. In coordination chemistry, hapticity is the coordination of a ligand to a metal center via an uninterrupted and contiguous series of atoms. [1] The hapticity of a ligand is described with the Greek letter η ('eta'). For example, η 2 describes a ligand that coordinates through 2 contiguous ...
