Mass spectrum 98
WebMass spectrum of methylcyclohexane. Methylcyclohexane has a molecular weight of 98; therefore the peak occurring at m/z = 98 represents the unfragmented, but positively … WebDetermining The Molecular Formula. Molecular Ion. Using mass spectrometry to determine the molecular ion allows us to identify possible molecular formulas. In the 70 eV EI spectrum, the highest m/z ion appears to be m/z 154. In the 13 eV EI spectrum, less fragmentation is observed because the ionization energy is much lower.

WebIn the mass spectrum, the heaviest ion (the one with the greatest m/z value) is likely to be the molecular ion. A few compounds have mass spectra which don't contain a molecular ion peak, because all the molecular ions break into fragments. That isn't a problem you are likely to meet at A'level. WebThe mass spectrum will typically establish the molecular weight and structure of the compound being analyzed. Mass spectra recorded under controlled conditions are highly …
WebLiterature reports [ 2] have indicated that principal peaks can be observed at m/z values equal to 309, 308, 165, 154, 121, 98, 56, and 55.
