The energy spectra of short rings of spin S = 1/2 particles with a nearest neighbour Heisenberg interaction have features which are common for various numbers N of spins. The example of N = 8 was considered in detail, for which a complete set of eigenstates and eigenvalues is obtained by the Bethe Ansatz model. The results were compared with the rotational band model usually used for the interpretation of experimental data for antiferromagnetic molecular magnets. (© 2005 WILEY‐VCH Verlag GmbH & Co.
