  2. Mass spectral interpretation - Wikipedia

    en.wikipedia.org/wiki/Mass_spectral_interpretation

    [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 spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...

  3. Palladium (II) chloride - Wikipedia

    en.wikipedia.org/wiki/Palladium(II)_chloride

    Palladium(II) chloride, also known as palladium dichloride and palladous chloride, are the chemical compounds with the formula PdCl 2.PdCl 2 is a common starting material in palladium chemistry – palladium-based catalysts are of particular value in organic synthesis.

  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. Mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Mass_spectrometry

    Mass spectrometry can measure molar mass, molecular structure, and sample purity. Each of these questions requires a different experimental procedure; therefore, adequate definition of the experimental goal is a prerequisite for collecting the proper data and successfully interpreting it.

    The initial product contains HCl, which is removed by heating. Alternatively, (carbonato)bis(ethylenediamine)cobalt(III) chloride reacts with hydrochloric acid at 10 °C to give the same species. [1] [Co(CO 3)(en) 2]Cl + 2 HCl → trans-[CoCl 2 (en) 2]Cl + CO 2 + H 2 O UV-vis spectra of various stages in the conversion of trans-[CoCl 2 (en) 2 ...

  7. Dichlorine hexoxide - Wikipedia

    en.wikipedia.org/wiki/Dichlorine_hexoxide

    Dichlorine hexoxide is the chemical compound with the molecular formula Cl 2 O 6, which is correct for its gaseous state. However, in liquid or solid form, this chlorine oxide ionizes into the dark red ionic compound chloryl perchlorate [ClO 2] + [ClO 4] −, which may be thought of as the mixed anhydride of chloric and perchloric acids. This ...

  8. Fragmentation (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Fragmentation_(mass...

    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.

  9. Chemical ionization - Wikipedia

    en.wikipedia.org/wiki/Chemical_ionization

    Peroxynitrate chemical ionization mass spectrometer at the US National Oceanic and Atmospheric Administration. CI mass spectrometry is a useful tool in structure elucidation of organic compounds. [3] This is possible with CI, because formation of [M+1] + eliminates a stable molecule, which can be used to guess the functional groups present. [3]
