NMR

Author: Dr Wainwright
Description:

Understand that nuclear magnetic resonance gives information about the position of 13C or 1H atoms in a molecule

Understand that 13C n.m.r. gives a simpler spectrum than 1H n.m.r.

Know the use of the δ scale for recording chemical shift

Understand that chemical shift depends on the molecular environment

Understand how integrated spectra indicate the relative numbers of 1H atoms in different environments

Understand that 1H n.m.r. spectra are obtained using samples dissolved in proton-free solvents

Understand why tetramethylsilane (TMS) is used as a standard

Be able to use the n +1 rule to deduce the spin–spin splitting patterns of adjacent, non-equivalent protons, limited to doublet, triplet and quartet formation in simple aliphatic compounds

Task

In time for the next lesson, you need to make some notes on nmr spectroscopy. These should be in your own words and should make up between 1-2 pages of an A4 sheet. This should be handwritten and ordered in the following subheadings:

How NMR Works, Chemical Shift, Tetramethysilane, Solvents for nmr, Integration Traces, Spin-spin coupling, N + 1 rule, MRI
