  3. 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.

  4. Tolyl group - Wikipedia

    en.wikipedia.org/wiki/Tolyl_group

    Structures of the three isomers of tolyl group. In organic chemistry, tolyl groups are functional groups related to toluene. [1] They have the general formula CH 3 C 6 H 4 −R, the change of the relative position of the methyl and the R substituent on the aromatic ring can generate three possible structural isomers 1,2 (ortho), 1,3 (meta), and 1,4 (para).

  5. Mass spectrum - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrum

    Electron ionization mass spectrum of toluene. Note parent peak corresponding to molecular mass M = 92 (C 7 H 8 +) and highest peak at M-1 = 91 (C 7 H 7 +, quasi-stable tropylium cation). 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 ...

    en.wikipedia.org/wiki/Toluene

    Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...

    In mass spectrometry, fragmentation is the dissociation of energetically unstable molecular ions formed from passing the molecules mass spectrum.These reactions are well documented over the decades and fragmentation patterns are useful to determine the molar weight and structural information of unknown molecules.
