  2. Bromophenol - Wikipedia

    en.wikipedia.org/wiki/Bromophenol

    Bromophenol. A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different bromophenols in total when ...

  3. Monobromophenol - Wikipedia

    en.wikipedia.org/wiki/Monobromophenol

    The monobromophenols are chemical compounds consisting of phenol substituted with a bromine atom. There are three isomers, 2-bromophenol, 3-bromophenol, and 4-bromophenol. Bromophenols. IUPAC name. 2-Bromophenol. 3-Bromophenol.

  4. Bromophenol blue - Wikipedia

    en.wikipedia.org/wiki/Bromophenol_blue

    Bromophenol is also used as a colour marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis.Since bromophenol blue carries a slight negative charge at moderate pH, it will migrate in the same direction as DNA or protein in a gel; the rate at which it migrates varies according to gel density and buffer composition, but in a typical 1% agarose gel in ...

  5. Bromoform - Wikipedia

    en.wikipedia.org/wiki/Bromoform

    Bromoform is an organic compound with the chemical formula CHBr3. It is a colorless liquid at room temperature, with a high refractive index and a very high density. Its sweet odor is similar to that of chloroform. It is one of the four haloforms, the others being fluoroform, chloroform, and iodoform.

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.

  7. Transfer-matrix method (optics) - Wikipedia

    en.wikipedia.org/wiki/Transfer-matrix_method...

    The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films. [ 1 ][ 2 ] This is, for example, relevant for the design of anti-reflective coatings and dielectric mirrors. The reflection of light from a single interface ...

    en.wikipedia.org/wiki/Dibromophenol

    Dibromophenol. Dibromophenols are a group of bromophenols consisting of one hydroxy group and two bromine atoms bonded to a benzene ring. There are six structural isomers, each with the molecular formula C 6 H 4 Br 2 O, which differ by arrangement of the substituents. Dibromophenols.

  9. Rydberg formula - Wikipedia

    en.wikipedia.org/wiki/Rydberg_formula

    In 1890, Rydberg proposed on a formula describing the relation between the wavelengths in spectral lines of alkali metals. [2]: v1:376 He noticed that lines came in series and he found that he could simplify his calculations using the wavenumber (the number of waves occupying the unit length, equal to 1/λ, the inverse of the wavelength) as his unit of measurement.
