4 cards from this section. Quick, good the night before a test.
What does the molecular ion represent in Mass Spectrometry?
Think about what happens during ionization.
Why is the base peak significant in a mass spectrum?
Consider what the highest peak indicates in relative terms.
What occurs during ionization of the sample in Mass Spectrometry?
Consider the two primary actions happening here.
True or False: The base peak represents the molecular ion.
Reflect on what the highest peak signifies in a spectrum.
A mass spectrometer provides a spectrum with a molecular ion peak at 200 m/z followed by a base peak at 100 m/z. Assuming the base peak represents a common fragment, what might this suggest about the molecular structure?
Think about how structure influences fragment stability.
If a mass spectrum shows an M+2 peak at one-third the height of the M+ peak, what element might be suspected in the compound?
Recall the ratio of isotopes for common halogens.
