Raman and far-infrared spectra of crystalline methylene iodide

The lattice vibrations and internal modes of polycrystalline CH2I2 and CD2I2 have been studied as a function of temperature using Raman and far‐infrared spectroscopy. CH2I2 has two stable phases, one of which is metastable in the temperature range of the other, and a second metastable phase. CD2I2 h...

Zusammenfassung:	The lattice vibrations and internal modes of polycrystalline CH2I2 and CD2I2 have been studied as a function of temperature using Raman and far‐infrared spectroscopy. CH2I2 has two stable phases, one of which is metastable in the temperature range of the other, and a second metastable phase. CD2I2 has only one solid phase. Possible structures for the various phases are discussed.
