The observed fundamentals of the cubic form of As4O6(arsenolite) are unambiguously assigned from single-crystal measurements. Data are also reported for the isomorphous senarmonite (Sb4O6) which (in the mineral) contains small quantities of the orthorhombic polymorph valentinite (Sb4O6). The gas-phase Raman spectra of P4O10, P4O6, and As4O6(together with polarization data) suggest that the cage structure is retained in the gas phase.
