How to find the molecular mass from a mass spectrum?
The mass charge value of the molecular ions peak is the molecular mass
What is a fragmentation pattern and how does it occur?
bombarding electrons make some of the molecular ions break up into fragments
The fragments that are ions show up on the mass spectrum, making
fragmentation patterns
they can be used to identify moelcules and their structure
What are the basic steps involved in working out the molecule from a mass
sprectrum?
1. Identify the fragments - look at the m/z peak of each molecule
2. Peice them together to form a moelcule with the correct Mr
Draw a diagram of a mass spectrometer
