WebJun 6, 2014 · At room temperature, cyclohexane gives one signal because interconversion of chair forms occurs rapidly. At low temperatures, however, it gives a very complex 1 H NMR spectrum. At low temperatures interconversions are slow; the chemical shifts of the axial and equatorial protons are resolved, and complex spin-spin couplings occur. http://butane.chem.uiuc.edu/jsmoore/chem232/notes_current/Cycloalkanes/NOTES-The_Conformations_of_Cyclohexane.pdf WebThere is a peak/local maximum at the boat conformation (C), and there are valleys/local minimums at the twist-boat conformations (B).
