Abstract:
The high-pressure behavior of dimethyl sulfide was investigated at room temperature by Raman scattering measurements with pressures up to 30.1 GPa. Phase transitions at 1.3, 3.6-5.8, and 17.2 GPa were found and evidenced by the frequency shifts, pressure coefficients, and changes in fwhm of related modes. These phase transitions were suggested to result from the changes in the inter- and intramolecular bonding of the material. Interestingly, the CH3 groups was compelled to be frozen in positions at a relatively low pressure, suggested by the disappearance of the relative modes softening. In addition, the appearance of lattice mode can also be found at a modest pressure, which makes it possible to gain a superiority for this compound to further investigate the superconductivity with high transition temperatures of bulk hydrogen.
