This internal is 3 credits and is completed in the last 3 weeks of term 2 and is due on Friday the 27th of June
Field Trip to UC on 24th of June to see the fancy spec equipment!
What is spectroscopy?
What is spectroscopy?
Spectroscopy is the analysis of data to identify unknown compounds. There are 3 types of data which are typically analyzed:
Infra- red
Mass
C13 NMR (Nuclear Magnetic Resonance)

Infra- Red Spectroscopy
Infra- Red Spectroscopy
IR is used to identify the functional groups present in the molecule. So it can tell you if there is an OH present or a double bond but it can't tell you where in the molecule these functional groups are located or how many of them they are.
Mass Spectroscopy
Mass Spectroscopy
Mass spectroscopy is used to identify the mass of the molecule and also the mass of chunks of the molecule.
The attached slides explain how the mass spectrometer machine works and how it helps us to identify unknown molecules.
There is no reference data for this but you will need a periodic table so you can see what mass numbers certain atoms are and hence be able to calculate what certain peaks correspond to.
Carbon 13 NMR
Carbon 13 NMR
This is used to identify the number of different carbon environments the molecule has. An environment is determined by what the carbon is bonded to. Symmetrical molecules will have carbon atoms which are in identical environments.
You will always be given this reference data

You will be given a paper copy of the internal with the respective data provided. Because this internal involves lots of writing of formula i highly suggest you write out your internal on paper but if you wish you can complete it via a google doc.
