Chemical shifts are variable and can vary depending on the solvent, concentration and substituents. As a result, shifts may be outside the ranges indicated
above.
OH and NH chemical shifts are very variable and are often broad. Signals are not usually seen as split peaks.
Note that CH bonded to ‘shifting groups’ on either side, e.g. O–CH2–C=O, may be shifted more than indicated above.
