Abstract: The Raman and infrared spectra of orthorhombic selenium were measured. The spectra are not explained by any structural models assuming the presence of hitherto-known molecules, that is, polymeric chains, Se 6 rings, and Se 8 rings. This suggests that orthorhombic selenium consists of unknown molecular species. This is supported by the experimental result that only the orthorhombic form can be recrystallized from a solution of orthorhombic selenium in carbon disulfide. The probability of the existence of Se 7 ring molecules in orthorhombic selenium is discussed.
