How NMR works
This is nuclear Magnetic resonance spectroscopy. It is a method used to study molecules of
different substance where the following information about a molecule can be obtained.
Diffusion coefficient, 2D and 3D image of the molecule, protein structure, molecular structure,
bond lengths and angle and the local coordination environment (pg. 2). It is a method that is
used in quality control and research when determining the purity and content of the samples
along with the molecular structure. All nuclei have a property known as a spin. The spin
numbers start from 0 and increase infinitely at rate of 0.5 depending on the atom. Each spin
has a given energy level and moment (pg. 3).
When determining the unknown compounds, the content is always weighed against the
content in the library. After determining the basic structure from the library, this method can
then be used to determine the molecular conformation as well as studying the physical
properties. Among the physical qualities include the solubility, phase change, diffusion and
conformational change. There are various techniques used in NMR (pg 4).
The energy emitted is given by
Δ E=h vl
Where Δ E is the energy change Vl if the Larmor frequency
