Isomers of the Sulfur Homocycles

The reliability of the energies in Table 17 follows from the good agreement between the experimental SS bond dissociation enthalpy of 150 2 kj mol and the relative enthalpy calculated for the eight-atomic Ss chain in its triplet ground state which is 154 kJ mol at 298 K [79]. 

To a certain extend isomers of other sulfur rings have also been discovered by theoretical methods. However, as far as known the activation energies for the transformation of the ground state conformation into the next most stable structure are quite high ( 25 kJ mol ) [69, 105]. An exception
