Experimental results of Raman scattering spectra of epsilon-InSe crystals are presented at 300 K and pressures up to 10.2 kbar. Values of the mode-Gruneisen parameters were calculated using frequency-pressure dependences for five observed phonons. Changes of the shear force constants under pressure were analysed using linear-chain model both for epsilon-InSe and epsilon-GaSe crystals. The decrease of the shear force constants between metallic planes with increasing pressure are explained qualitatively by charge transfer from intralayer to interlayer space.
