Raman Spectroscopy at High Pressures

Figure 4

Representative temperature-dependent Raman spectra of H2 obtained in the laser-heated DAC. Left and right panels correspond to the spectral ranges of rotational and vibrational transitions. The curves at each temperature correspond to the same measurement. The vibron amplitude at 300 K is approximately five-times larger than that of the strongest roton band. The spectral positions of the roton bands are shown with vertical ticks. The phonon band is marked by an arrow.
