Analytical techniques I & II Flashcards
1
Q
What is NMR spec
A
an analytical technique that allows the structure of a molecule to be determined by analysing bond & atom environments.
2
Q
What is an environment of an atom
A
the surrounding atoms and bonds in the molecule.
3
Q
What is the molecular ion peak
A
a mass spectrometer trace is the whole compound as an ion (so gives Mr).
4
Q
What is the fingerprint region used for
A
can be used as a comparison to identify something.
5
Q
When does fragmentation occur
A
occurs when molecules break into smaller pieces in a mass spectrometer.
