Abstract
We report on the IR spectroscopic studies in both reflection (50-900 cm(-1) ) and transmission (900-3000 cm(-1)) mode of the vibration spectrum of cupr ous oxide. A detailed analysis based on a comparison of the temperature dep endences of the absorption band at similar or equal to 1125 cm(-1) and of I R and Raman active fundamental vibrations results in assignment of the form er to a biphonon.
