(dithiolene) complexes has been revolutionized recently by involvement of sulfur K-edge X-
ray absorption spectroscopy (XAS) to directly probe the sulfur composition of the frontier
orbitals. In concert with other spectroscopic methods, and increasingly theoretical
calculations, a more accurate electronic structure description has been delivered. The
methodology developed has also been applied to mono (dithiolene) and tris (dithiolene) …
