Anatomy of a H1 NMR Spectrum Flashcards
1
Q
What is the x-axis known as
A
Chemical Shift
2
Q
What’s the importance of the Y-axis
A
No importance
3
Q
What’s used instead of the Y-axis
A
The relative intensity of the signals called Integration. This is proportional to the number of protons.
4
Q
The shape of a H1 NMR spectrum is also known as
A
Multiplicity
5
Q
What is multiplicity
A
number of peaks on each signal influenced by number of neighbours
6
Q
If there are zero neighbours how many wave lengths will there be
A
1
7
Q
If there are one neighbour how many wavelengths will they be
A
2
8
Q
What is the chemical shift largely influenced by
A
electron density
9
Q
If a proton has a high chemical shift is it shielded or deshielded
A
De-shielded
10
Q
Why are there sometimes multiple peaks
A
due to the presence of neighbouring protons
