Information from NMR spectrum… |
…and what it tells
us (in layman’s terms) |
|
|
Integral |
number of hydrogens in that set (how many?) |
|
|
Splitting |
number of hydrogens in each set of equivalent hydrogens on adjacent carbons calculated with the n + 1 rule (what’s next door?) |
|
|
Chemical Shift |
Chemical and electronic environment (where am I?) |
Where a set refers to a group of chemically, stereochemically and electronically equivalent hydrogens.
How do I determine… |
|
|
|
…the Integral? |
Count |
|
|
…who the neighbors are? |
Interpret the splitting pattern and use the n + 1 rule |
|
|
…what the chemical shift means? |
Remember information from the following diagram: |
