Vibrational spectra of hexahalocyclopropanes and tetrahalocyclopropenes

Abstract

Raman and infra-red spectra are reported for hexachlorocyclopropane (I), hexa-bromocyclopropane (II), hexafluorocyclopropane (III), tetrachlorocyclopropene (IV) and tetra-bromocyclopropene (V). A vibrational assignment is made for I, II and III on the basis of D_3h symmetry and for IV and V on the basis Of C_2v symmetry.
