We have measured lattice parameters and Raman spectra of hexagonal graphite at pressures up to the structural phase transition near 14 CiPa (T =300 K). The frequencies of the E2g(1) rigid-layer shear mode at 44 cm ' and the E2g(2) in-plane mode at 1579 cm ' increase sublinearly under pressure with i
