The infrared spectra of solid oxygen, in the overtone region, have been measured in the ? and in the ? phases at low and room temperature up to 60 GPa. The two structured bands observed in the ? phase are assigned to the combination of the infrared active mode with itself and with the Raman active mode, respectively. Performing a deconvolution of the spectral profile the densities of states of the infrared and Raman active vibrational modes are obtained.

Abstract
The infrared spectra of solid oxygen, in the overtone region, have been measured in the ? and in the ? phases at low and room temperature up to 60 GPa. The two structured bands observed in the ? phase are assigned to the combination of the infrared active mode with itself and with the Raman active mode, respectively. Performing a deconvolution of the spectral profile the densities of states of the infrared and Raman active vibrational modes are obtained.File in questo prodotto:
