Reversible 1,2‐shifts of the ethyl group in the 9‐ethyl‐9, 10‐dimethylphenanthrenonium ion lead to a reversible change of the ring hydrogen states (A′B′C′D′ ⇄ A″B″C″D″). Line shape analysis for the determination of the exchange rate was performed for this case of intramolecular exchange between the two multi‐spin systems. The calculations are based on density matrix formalism.
