L39 - NMR And MRI - Advance Interpretation Flashcards
1
Q
How can you measure coupling?
A
- measure a, measure b
- measure spliiting for a, how far a ppm is for b
- divide a by b, multiply by the Hz per ppm
2
Q
What is coupling constant?
A
Protons couple to each other, with certain intensity (vary from 0 to 18 Hz, usually ~ 7)
3
Q
What happens when a molecule contains a proton which is coupled to 2 different protons with different coupling constants?
A
Different splitting pattern
