How does mass spec work
Vaporises sample
Changes to positively charged ions
What are the uses of mass spec
RAM of element
RFM of compound
Existence of isotopes + relative abundances
Molecular groups in compounds - fragmentation pattern
Identify structure
Mechanism of a reaction
What is the definition of an m+1 peak
Peak produced by a molecular ion with an increased mass due to the presence of one c-13 atom
What does the m+1 peak allow you to measure and what is the % abundance of one c13
The number of C in a molecule
1.1%
What is the general equation when a molecular ion is formed
M(g) ➡️ M+(g) + e-
What is the definition of a fragmentation ion
A positively charged ion produced when the molecular ion breaks apart
What is the definition of a molecular ion peak
Peak formed by an ion formed by the removal of one e- from a molecule
What is the definition of base peak
Peak of greatest abundance in a mass spectrum
