"Direct" determination of the Gruneisen parameter of the LTO(Γ) mode of diamond at high pressures
Aleksandrov I. V., Goncharov A. F., Stishov S. M.
The first-order Raman scattering spectra of diamond have been measured at pressures up to 42 GPa. The lattice constant was measured simultaneously. The results show that the Griineisen parameter of the LTO (Γ) mode of diamond is essentially independent of the density.
