Figure 6. Synchrotron micro-IR and inelastic neutron scattering (INS) spectra for MFM-300(V).

Comparison of (a) the synchrotron micro-IR spectra and (b) INS spectra for bare MFM-300(V^III) and MFM-300(V^IV). IR and INS spectra offer vibrational information on the –OH stretching and deformation region, respectively, and are thus complementary. (c) Comparison of the INS spectra for bare and CO₂-loaded MFM-300(V^III); (d) difference spectra for both experiment and calculation showing changes of the H motion from the local MOF upon CO₂ binding in MFM-300(V^III). (e) Comparison of the INS spectra for bare and CO₂-loaded MFM-300(V^IV); (f) difference spectra for both experiment and calculation showing changes of the H motion from the local MOF upon CO₂ binding in MFM-300(V^IV). Synchrotron IR and INS data were collected at 298 and 10 K, respectively.
