Abstract
The Raman frequency shifts calculated for the pressure-induced librons and vibron, agree with the experimental frequency shifts in most cases, in particular at low pressures for αâO2. This shows that the Raman frequency shifts can be calculated adequately from the volume by means of the mode Grüneisen parameter using the method given here for the α-phase of oxygen or more generally for molecular solids.
