The lattice vibrations and internal modes of polycrystalline CH 2 I 2 and CD 2 I 2 have been studied as a function of temperature using Raman and far‐infrared spectroscopy. CH 2 I 2 has two stable phases, one of which is metastable in the temperature range of the other, and a second metastable phase. CD 2 I 2 has only one solid phase. Possible structures for the various phases are discussed.
