Predicted spectra

WebJun 5, 2012 · As a group, list three reasons that the actual mass spectra is different from the predicted spectra. Abundances are different because stability of the fragments determines the number of fragments found. Some fragments do not form due to the likelihood of breaking bonds. Isotopes cause the masses of some fragments to be slightly different. WebPlease help with this: Are there any differences between the spectra you obtained in Beyond Labz and the predicted spectra? If so, what were the differences? The first one is what I predicted and the second one are the actual results but. I don't know how to really put it in words. Show transcribed image text.
