As a result, information about the nucleus' chemical environment can be derived from its resonant frequency.In general, the more electronegative the nucleus is, the higher the resonant frequency.The signal that matches this transfer is measured in many ways and processed in order to yield an NMR spectrum for the nucleus concerned. The precise resonant frequency of the energy transition is dependent on the effective magnetic field at the nucleus.

Also, you would need a table caption at the top, explaining briefly what the table is showing.

Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and reserach for determining the content and purity of a sample as well as its molecular structure.

For example, NMR can quantitatively analyze mixtures containing known compounds.

This is because the precise resonant frequency shift of each nucleus depends on the magnetic field used.

The frequency is not easy to remember (for example, the frequency of benzene might be 400.132869 MHz) so it was decided to define chemical shift as follows to yield a more convenient number such as 7.17 ppm.

has provided you with an excellent template in the preceding answer.

The lab report below was submitted as part of the coursework for CM2102 Spectroscopic Applications.

In order to achieve the desired results, a variety of NMR techniques are available. If an external magnetic field is applied, an energy transfer is possible between the base energy to a higher energy level (generally a single energy gap).

The energy transfer takes place at a wavelength that corresponds to radio frequencies and when the spin returns to its base level, energy is emitted at the same frequency. The basis of NMR Fig.1, above, relates to spin-½ nuclei that include the most commonly used NMR nucleus, proton (H or hydrogen-2) have a higher spin and are therefore quadrupolar and although they yield NMR spectra their energy diagram and some of their properties are different.
