Abstract
- Raman used to examine high pressure polymorphism of acetylsalicylic acid, aspirin.
- Pressure effects on two polymorphs, Aspirin-I and II, examined to 10Â GPa.
- Raman spectra indicted transformation of Aspirin-I to a new Aspirin-III above 2Â GPa.
- Aspirin-I to Aspirin-III transition involved rearrangement in acetyl groups.
- Aspirin-II showed no phase change but gradual disordering of structure above 7Â GPa.
