    en.wikipedia.org/wiki/Absolute_configuration

    COOH, R, NH 2 and H (where R is the side-chain) are arranged around the chiral center carbon atom. With the hydrogen atom away from the viewer, if the arrangement of the CO→R→N groups around the carbon atom as center is counter-clockwise, then it is the L form. [14] If the arrangement is clockwise, it is the D form. As usual, if the ...

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

    For example, the ideal gas law in terms of the Boltzmann constant is: P V = N k B T , {\displaystyle PV=Nk_{\rm {B}}T,} where N is the number of particles (molecules in this case), or to generalize to an inhomogeneous system the local form holds:

    chemical physics A branch of chemistry and physics that studies chemical processes from the point of view of physics by investigating physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics. chromatic aberration circular motion classical mechanics. Also called Newtonian mechanics.

  7. Retardation factor - Wikipedia

    en.wikipedia.org/wiki/Retardation_factor

    An R F value will always be in the range 0 to 1; if the substance moves, it can only move in the direction of the solvent flow, and cannot move faster than the solvent. For example, if particular substance in an unknown mixture travels 2.5 cm and the solvent front travels 5.0 cm, the retardation factor would be 0.50.

  8. Rydberg constant - Wikipedia

    en.wikipedia.org/wiki/Rydberg_constant

    The hydrogen spectral series can be expressed simply in terms of the Rydberg constant for hydrogen and the Rydberg formula. In atomic physics , Rydberg unit of energy , symbol Ry, corresponds to the energy of the photon whose wavenumber is the Rydberg constant, i.e. the ionization energy of the hydrogen atom in a simplified Bohr model.
