  2. Bromobenzene - Wikipedia

    en.wikipedia.org/wiki/Bromobenzene

    Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is C 6 H 5 Br . It is a colourless liquid although older samples can appear yellow.

  3. Hexabromobenzene - Wikipedia

    en.wikipedia.org/wiki/Hexabromobenzene

    Molar mass: 551.490 g·mol −1 Appearance ... The acute toxicity of brominated benzenes decreases with an increase in the number of bromine atoms in the molecule. [11]

  4. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...

  5. 1,2,4,5-Tetrabromobenzene - Wikipedia

    en.wikipedia.org/wiki/1,2,4,5-Tetrabromobenzene

    1,2,4,5-Tetrabromobenzene is an aryl bromide and a four-substituted bromobenzene with the formula C 6 H 2 Br 4. It is one of three isomers of tetrabromobenzene. The compound is a white solid. 1,2,4,5-Tetrabromobenzene is an important metabolite of the flame retardant hexabromobenzene. [1]

  6. Atomic spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_spectroscopy

    The relationship between the concentration of atoms, the distance the light travels through the collection of atoms, and the portion of the light absorbed is given by the Beer–Lambert law. In atomic emission spectroscopy, the intensity of the emitted light is directly proportional to the concentration of atoms.

  7. Bromobenzenes - Wikipedia

    en.wikipedia.org/wiki/Bromobenzenes

    Bromobenzenes are a group of aryl bromides/halobenzenes consisting of one or more bromine atoms as substituents on a benzene core. They have the formula C 6 H 6–n Br n, where n = 1–6 is the number of bromine atoms. Depending on the number of bromine substituents, there may be several constitutional isomers possible.

  8. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    Mass spectral interpretation is the method employed to identify the chemical formula, characteristic fragment patterns and possible fragment ions from the mass spectra. [1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass ...

  9. Spectroscopic notation - Wikipedia

    en.wikipedia.org/wiki/Spectroscopic_notation

    Spectroscopists customarily refer to the spectrum arising from a given ionization state of a given element by the element's symbol followed by a Roman numeral. The numeral I is used for spectral lines associated with the neutral element, II for those from the first ionization state, III for those from the second ionization state, and so on. [ 1 ]
