Spectroscopic Evidence for Pseudorotation of Seven-Membered Chalcogen Rings in Solution [1]

Steudel, Ralf; Papavassiliou, Maria; Jensen, Detlef; Seppelt, Konrad

The 77Se NMR spectrum of l,2-Se2S5 exhibits one singlet at 1077.3 ppm indicating pseudorotation in solution; the same conclusion is reached from the solution Raman spectrum of S7 showing characteristic line broadening compared to the solid state spectrum.
