Abstract
In this article, we report a high-pressure Raman spectroscopy study of
palmitic acid (PA, C form) from ambient pressure up to 21 GPa. The
effects of hydrostatic pressure on the vibrational spectrum of PA are
reported, and the data show that PA experiences a rich sequence of phase
transformations. These changes in the crystal structure occur gradually
as the pressure increases and they are related to the highly flexible
crystalline structure. Copyright (c) 2011 John Wiley & Sons, Ltd.
