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

If your instructor has not specified a format, Truong-Son N.

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.

Depending on its chemical environment, the protons in a molecule resonate at slightly different frequencies.

The variation of the resonance frequency with chemical environment is known as the chemical shift.

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.

This field is affected by electron shielding which is in turn dependent on the chemical environment.
