Web24 de oct. de 2024 · The spectrum contains only two majors peak: the molecular ion at m / z = 218 amu and a fragment at m / z = 109 amu. The original data is available here. … WebIn 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 pattern is useful to determine the molar weight and structural information of the unknown molecule.

WebPeroxynitrate 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] Web1.
