Introductory note on the 1H NMR spectra of cyclohexane

Students and teachers please note my explanation of the proton NMR spectrum of cyclohexane is designed for advanced, but pre-university, chemistry courses.

The chemical shift δ splitting pattern effects for cyclohexane are confined to a proton spin-spin coupling effects analysed using the n+1 rule for adjacent non-equivalent proton fields (n is the number of neighbouring protons in a non-equivalent different chemical environment for the cyclohexane molecule).

It is assumed that the integrated intensities of the 1H NMR δ chemical shifts give the ratio of the protons in the different non-equivalent chemical environments of the cyclohexane molecule.

The most common solvent used for investigating the 1H NMR spectrum of compounds like cyclohexane, is CDCl3 and other deuterated solvents to avoid confusion with a 1H NMR signal, 2D (2H) has a different NMR chemical shift.

TMS is the acronym for tetramethylsilane, formula Si(CH3)4, whose protons are arbitrarily given a chemical shift of 0.0 ppm. This is the 'standard' in 1H NMR spectroscopy and all other proton shifts, called chemical shifts, depend on the individual (electronic) chemical environment of the hydrogen atoms in an organic molecule - cyclohexane here.

The chemical shifts quoted in ppm on the diagram of the H-1 NMR spectrum of cyclohexane represent the peaks of the intensity of the chemical shifts of (which are often groups of split lines at high resolution) AND the relative integrated areas under the peaks gives you the ratio of protons in the different chemical environments of the cyclohexane molecule.

The hydrogen atoms (protons) of cyclohexane occupy just one unique chemical environment shown by the observation of just one 1H NMR spectral line at 1.43 ppm.

Although there are 12 hydrogen atoms in the molecule, there is only one possible chemical environment for the hydrogen atoms in the cyclohexane molecule.

All 12 hydrogen atoms in cyclohexane are equivalent to each other and their 1H fields cannot cause spin-spin coupling splitting effects in the hydrogen-1 NMR spectrum.

The cyclohexane molecule is a symmetrical molecule on a time averaged basis, ignoring conformational analysis, hence all 12 protons inhabit the same electronic chemical environment.

The splitting pattern from proton spin-spin coupling effects is analysed using the n+1 rule for adjacent non-equivalent proton fields (n is the number of neighbouring protons in a non-equivalent different chemical environment).
