Cyclohexane chemical shift

Webcyclohexane). On the other hand, strong solvent effects can be used in order to "simplify" the spectrum: if an aromatic solvent such as benzene is used, then this will solvate areas of low electron density and, due to ring current effects, this can change chemical shifts by as much as 1 ppm. WebList them as they would appear in an NMR spectrum, e.g. by decreasing chemical shift with the lowest shift to the right.
