Properties of Sulfur‐Sulfur Bonds
TL;DR: In this article, the authors show that SS bonds are extraordinarily flexible and have properties that are observed only on isolated occasions for other homonuclear bonds: the bond lengths very between 1.8 and 3.0A, the bond angles between 90 and 180° and the dihedral angles between 0 and 360°; the bond energies amount to up to 430 kJ/mol.

Vibrational assignment and force constants of S8 from a normal-coordinate treatment
TL;DR: In this article, normal coordinate calculations for S8 were revised by using of new far-infrared spectral data that locate the low infrared-active fundamentals at 191 (e1) and 243 (b2) cm−1 (solution state).
