1bromo2chloroethane Mass Spectrum
Regarding the mass spectrometry of 1-bromo-2-chloroethane
Now there is 1-bromo-2-chloroethane, to clarify its mass spectrometry. In this compound, bromine and chlorine each have unique isotopic characteristics. Bromine has two isotopes of similar abundance, namely\ (^ {79} Br\) and\ (^ {81} Br\), and chlorine also has two isotopes,\ (^ {35} Cl\) and\ (^ {37} Cl\).
During mass spectrometry analysis, the molecular ion peak of 1-bromo-2-chloroethane presents a unique peak cluster due to bromine and chlorine isotopes. If the molecular ion peak is\ (M\), then the\ (M + 2\) peak will appear due to the bromine isotope, and the intensity of the two is similar to\ (1:1\). And because of the chlorine isotope, the\ (M\) and\ (M + 2\) peaks are respectively derived from the\ (M + 2\) and\ (M + 4\) peaks contributed by the chlorine isotope.
Fragment ion peaks, the fracture of the carbon-bromide bond or the carbon-chlorine bond will produce corresponding fragments. The fracture of the carbon-bromide bond generates chlorine-containing fragment ions, and the mass-to-charge ratio depends on the fragment structure. Fracture of carbon-chlorine bond produces fragment ions containing bromine. The intensity of these fragment ion peaks is easily related to the difficulty of chemical bond fracture. The lower the chemical bond energy, the higher the probability of fracture, the higher the intensity of the corresponding fragment ion peaks.
Through the analysis of molecular ion peaks and fragment ion peaks in 1-bromo-2-chloroethane mass spectrometry, the molecular structure and chemical bond properties can be determined, which provides an important basis for the identification and structural analysis of organic compounds.
