In the differential spectra,the perturbed benzenering stretching bands ν18a,ν19b,ν19a modes,benzene ring deformation
modes σ12,ν(COO),ρ(CH2) of ted linkers are partially
recovered after the removal of the dominant,less strongly
bound SO2 molecules upon evacuation at room temperature.
Comparison of Figures 4 and 5 indicates that the weakly
bound SO2 (characterized by modes at 1326 cm-1 and 1144 cm-
1) causes the σ12 mode to blue shift by 4 cm-1 while the more
strongly bound SO2 characterized by modes at 1242 cm-1 and
1105 cm-1 causes the σ12 mode red shift to 732 cm-1.The perturbation
of the ν(COO),ν(CH2),δ(COO) bands and the benzene
deformation mode σ12 is removed after this latter species,
characterized by modes at 1242 cm-1 and 1105 cm-1,has desorbed
at elevated temperatures.
