Finding molecular formula from mass spectrum

WebCalculating the total molecular mass = 7 (12) + 8(1) + 16 = 108. There is still space to accommodate 136-108 = 28 units of mass. H is a light atom so we will first try to make some combinations with the heavier C and O atoms. 2 C-atoms = 2(12) = 24. 2 O-atoms = 2(16) = 32. 1 C and 1 O-atom = 12+ 16 = 28.

WebJul 23, 2024 · Here’s an example: Given the IR and NMR spectra for compound C 5 H 10 O, identify the fragments. From the NMR (shown in the figure), you determine that the whole number relative ratio for the molecule is 2:3:2:3. From the table, the most likely fragments for 2H, 3H, 2H, and 3H are CH 2, CH 3, CH 2, and CH 3, respectively. WebSince a molecule of carbon dioxide is composed of only three atoms, its mass spectrum is very simple. The molecular ion is also the base peak, and the only fragment ions are CO (m/z=28) and O (m/z=16). The molecular ion of propane also has m/z=44, but it is not the most abundant ion in the spectrum.
