ChemistrySpectroscopyASOCR Created by: anabobCreated on: 26-01-18 16:26 what can you find out from mass spec? atomic mass of elements, relative abundance of isotopes in an element. 1 of 7 what can you assume the m/z value is equal to? the molecular mass of th ion causing the peak 2 of 7 what is the molecular ion (M+)? heaviest ion, with just one electron removed. Tells the chemist what the molecular mass of the compound is 3 of 7 why are there peaks below the M+ peak? becuase it fragments 4 of 7 what's the fragmentation pattern? the way a parent ion breaks down is characteristi of the compound. 5 of 7 what is the base peak? most abundant ion 6 of 7 why is there sometimes a small M+1 peak? if a compund has incorporated a C13 7 of 7
