The 1H NMR spectrum of tropylium fluoroborate dissolved and oriented in a lyotropic decyl sulphate phase has been recorded and analysed. Direct as well as indirect HH coupling constants have been obtained. The vibrationally uncorrected proton skeleton structure deviates slightly from a regular heptagon. The deviations are between two and three times larger than those of benzene from a hexagon, previously observed in the same solvent.
