Figure 3

IR spectra of the GA, CCFs and their cocrystals (A,B) and simulated plausible models of the interactions (hydrogen bonds are marked using dashed lined) between GA and CCF cocrystals (C,D). Modeling was conducted using a GAUSSIAN-03 program package at the DFT B3lyp/6-31**level A, B: (a) GA; (b) CCF (glutaric acid in A and succinimide in B); (c) cocrystal.
