Overview

Cryogenic ion vibrational spectroscopy reveals distinct vibrational spectra of isomers, highlighting the role of hydrogen bonding.

Key Points

  • Distinct vibrational spectra enable the identification of isomers with identical functional groups.
  • The deprotonated states of valine and aminovaleric acid display unique IR signatures linked to hydrogen bonding.
  • Aminovaleric acid poses challenges in conformational search due to numerous potential conformations.
  • Lowest energy conformers for valine and aminovaleric acid are likely to be present in their deprotonated states.
