4 cards from this section. Quick, good the night before a test.
What is ionization in mass spectrometry?
Think about what happens when the sample is bombarded with electrons.
What does the molecular ion peak in a mass spectrum indicate?
Consider the significance of M⁺ in your analysis.
What is the purpose of ionization in mass spectrometry?
Remember why we need charged particles for analysis.
True or False: The base peak represents the molecular ion.
Different peaks can reflect different aspects of the molecule.
Explain how you would deduce the molecular structure of a compound given its mass spectrum displaying a clear molecular ion peak and multiple fragment peaks.
Use both mass-to-charge ratios and known fragment characteristics (e.g., specific m/z values) to support your deductions.
You are presented with a mass spectrum showing a prominent M+ peak and a relative abundance of isotope peaks. How would this assist in determining the number of carbon atoms in the compound?
Remember the formula for estimating carbon counts using isotope intensity ratios.
