Abstract
Raman spectroscopic studies of DL-serine and DL-valine under static high pressures have been carried out up to 8 and 7 GPa, respectively to understand the behaviour of hydrogen bonds in these compounds. The discontinuous changes in the pressure dependence of some of the Raman modes of DL-serine at 1.5 GPa are interpreted to be due to molecular rearrangements brought about by changes in the hydrogen bonding interactions. Our results of the pressure dependence of N-H···O librational modes in DL-valine at 3 GPa suggest changes in the nature of hydrogen bonding interactions across this pressure.
