A joint effort: By means of high-resolution rotational spectroscopy and highly accurate quantum-chemical calculations, the first observation and characterization of cyclic SiS2 was achieved. This provides a new perspective on the Walsh rules: Although the cyclic form of SiS2 is a local and not the global minimum, cyclic isomers of sixteen-electron triatomics containing second or even higher row elements are experimentally accessible.
