Raman Spectroscopy for Probing guest-host interactions in Metal Organic Frameworks
Published online by Cambridge University Press: 22 August 2011
Abstract
Spectroscopic techniques such as IR and Raman are very powerful to understand guest-host interactions. Although these techniques are complementary, Raman spectroscopy has not been widely implemented as a tool to characterize these interactions. This study illustrates the use of Raman spectroscopy not only to probe the interactions experienced by a guest molecule but also to detect structural changes occurring in the framework upon loading. Weak interactions of adsorbed molecules with the framework are reflected in frequency and intensity variations in both Raman and IR absorption lines, as shown for the case of CO2, N2 and CH4 with Zn(bdc)(ted)0.5.
