New cards

How are molecular ions formed?

Molecules being bombarded by electrons

2
New cards

Which peak is the molecular ion peak?

The one with the highest m/z value excluding the small peak that will be caused so C-13 isotopes

3
New cards

What does the molecular ion peak tell you?

The relative molecular mass

4
New cards

How are fragments made?

Some of the molecular ions are broken into fragments and free radicals by the electrons

5
New cards

What can and can’t be seen on a mass spectrum?

Fragments can be see but free radicals can’t

6
New cards

How can you distinguish between compounds with the same Mr using mass spectrometry?

They will have different fragments. All compounds produce different mass spectrums
