The ESR spectrum of the radical‐anion of [ 18 ]annulene‐1,4;7,10;13,16‐trisulfide (ATS) has been recorded. Its analysis yields six coupling constants for pair of equivalent protons indicating the lack of a threefold symmetry axis. A provisional assignment has been attempted which is based on calculated spinpopulations. Conformations of ATS and ATS ⊖ are shortly discussed.
