Metal-Organic Frameworks (MOFs) are a class of hybrid crystalline porous materials extensively researched in the last two decades with promising applications in fields like catalysis or gas capture and separation. Still being crystalline, some of the properties of such materials are due to disordered features, e.g. defects and mixed-metal clusters: in order to characterize those species the use of local techniques, like vibrational spectroscopies, are mandatory. The present contribution deals with the potentialities of IR and Raman spectroscopies in MOFs, also coupled with the in-situ dosage of probe molecules and the simulation of the vibrational spectra; some cases will be discussed together with the strengths and weaknesses of these spectroscopies in relation with other techniques classically adopted in characterizing these materials: X-ray diffraction and X-ray absorption spectroscopies.
