2
Q
Stages is mass spec
A
Ionisation
Acceleration
Deflection
Detection
3

5
Q
What and where is the molecular ion peak
A
Toward the far right
Molecular ion : when molecule looses one electron
6
Q
What does molecular peak equal
A
Mr of the molecular ion
7
Q
How do infrared spectrums come about
A
Shining infrared on sample
Some is transmitted some is absorbed
This is detected by detector
Specific bonds have specific ranges of IR
8
Q
What would be a difference in IR spec of 2 isomers with the same functional group
A
Difference in finger print regions / below 1500
