Cryobaric Raman measurements are reported for amorphous (a-) GeS//2 at 13K to 56 kbar. Hydrostaticity in a diamond-anvil cell is maintained by an argon pressure-transmitting medium. Pressure-induced peak shifts are fractionally small and reversible. However, peak broadenings are large (approximately 50-100%) and metastably retained, along with a newly emergent peak at 486cm** minus **1, after pressure release and dark-annealing. Evdence is found for pressure-assisted quasicrystallization at P equals 56 kbar. These results support a molecular model in which pressure squeezes out free (intermolecular) volume.
