  The IR and Raman spectra of the two polymorphic forms, I and II, of progesterone (pregn-4-ene-3,20-dione) have been examined under high pressures up to about 50 kbar using a diamond-anvil cell. Both polymorphs undergo structural changes in the 15-20 kbar pressure range. There is no convincing evidence for the conversion of form II into the more thermodynamically stable form I.
