Revealing Spectral Characteristics of Shared Protons in Deprotonated Glutamic Acid Using Cryogenic Ion Trap Spectroscopy and Anharmonic Calculations
Shared protons in dicarboxylate motifs are essential biological components. Infrared (IR) spectroscopy is the premier tool to probe the OHO vibrations defining these structures, as vibrational frequencies directly reflect the underlying potential surface. Previously, infrared multiple photon dissociation (IRMPD) studie...
