Progress in the Characterization of the Surface Species in Activated Carbons by means of INS Spectroscopy Coupled with Detailed DFT Calculations
Figure 3
Calculated INS vibrational modes for Model 1 in region (ii). Carbon atoms are grey, hydrogen atoms white, and displacement vectors red arrows. The contribution at 873 cm−1 is clearly connected to an in-phase oscillation of solo species on well-extended borders, while the intense mode at 958 cm−1 is connected to out-of-phase modes at duo, trio, and quatro sites that characterize a defective and not extended border.
