  2. Ellman's reagent - Wikipedia

    en.wikipedia.org/wiki/Ellman's_reagent

    Ellman's original 1959 publication estimated the molar extinction at 13,600 M −1 cm −1, and this value can be found in some modern applications of the method despite improved determinations. [6] Commercial DTNB may not be completely pure, so may require recrystallization to obtain completely accurate and reproducible results.

    A. R. Forouhi and I. Bloomer deduced dispersion equations for the refractive index, n, and extinction coefficient, k, which were published in 1986 [1] and 1988. [2] The 1986 publication relates to amorphous materials, while the 1988 publication relates to crystalline.

    en.wikipedia.org/wiki/Tert-Butanesulfinamide

    tert-Butanesulfinamide (also known as 2-methyl-2-propanesulfinamide or Ellman's sulfinamide) is an organosulfur compound and a member of the class of sulfinamides. Both enantiomeric forms are commercially available and are used in asymmetric synthesis as chiral auxiliaries , often as chiral ammonia equivalents for the synthesis of amines .

  7. Extinction coefficient - Wikipedia

    en.wikipedia.org/wiki/Extinction_coefficient

    Extinction coefficient refers to several different measures of the absorption of light in a medium: Attenuation coefficient , sometimes called "extinction coefficient" in meteorology or climatology Mass extinction coefficient , how strongly a substance absorbs light at a given wavelength, per mass density

    Eye diagram showing an example of two power levels in an OOK modulation scheme, which can be used to calculate extinction ratio. P 1 and P 0 are represented by (binary 1) and (binary 0) respectively. In telecommunications, extinction ratio (r e) is the ratio of two optical power levels of a digital signal generated by an optical source, e.g., a ...

  9. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. [ 1 ] [ 2 ] The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
