Spectroscopic evidence of reversible micro-crystallization of carbon dioxide dissolved in solid xenon

FTIR spectra of CO2 dissolved in liquid and solid Xe have been studied in similar to 1000 divided by 6000 cm(-1) frequency domain at T similar to 170 divided by 100 K. Apart a set of the fundamental and combination bands of the solute CO2, a set of new bands ascribed to crystalline CO2 have been found in the solid species. The crystallization process is reversible with respect to temperature variations. The qualitative change of the intensity ratio between the low-and high frequency components of the Fermi resonance Pi(u) doublet (11(1)0)(I)/(11(1)0)(II) has been revealed for the crystalline CO2.
