摘要
An extensive infrared absorption study of the compound Ar(H2)2in the range of pressure from 5 to 30 GPa, and between 30 K and room temperature is presented. This study has permitted the identification and assignment of high–frequency and low frequency vibron–phonon combination bands, as well as of the roto–vibrational bands. Spectra changes lowering temperature, with the appearance of the Q1(0) vibrational peak, are interpreted as arising from conversion of ortho–hydrogen into para–hydrogen in the solid.
