Hydrogen bond interactions in zwitterionic glycine.H2O complexes were investigated using Fourier transform infrared methodology and density functional theory (DFT). It was observed that a set of characterstic infrared absorption bands occurs in low temperature argon (Ar) matrices for the zwitterionic structure. It was observed that conformation I of glycine was slightly more stable than conformation III in Ar matrices. It was also observed that partial proton transfer towards a zwitterionic glycine.water structure was due to annealing matrices glycine/H2O/Ar with larger water/Ar ratio.
