NMR and spectroscopy Flashcards
1
Q
Why is CDCl3 used as a solvent in H NMR spectroscopy?
A
The solvent does not have any hydrogen/protons
Doesn’t show up on the spectrum
2
Q
Uses of NMR
A
MRI
body scanning
3
Q
What is the standard for chemical shift measurements?
A
TMS, (CH3)4 Si
4
Q
What is the putpose of D2O
A
Removes OH, COOH and NH peaks which could confuse the spectrum reading
5
Q
Rule for splitting
A
n + 1
n = adjacent hydrogens
