2. Ab-initio quantum-mechanical GIAO calculation of the anisotropic effect of C–C and X–C single bonds—application to the1H NMR spectrum of cyclohexane

3. Rationalization of the anomalous 1H NMR chemical shifts in 1,3-diheterocyclohexanes

4. It is noteworthy that fundamental structural problems in organic chemistry, like the understanding of the forces leading to the relative stabilization of the different conformers in ethane and butane, are currently under intense research. Some relevant references are:

5. The Case for Steric Repulsion Causing the Staggered Conformation of Ethane
