Zeolitic imidazole framework-8 (ZIF 8) is apromising metal-organic framework (MOF) for the storage, separation, anddetection of gases at room temperature and atmospheric pressure. Intermolecularinteractions between ZIF-8 and adsorbed gas molecules which perform animportant role in the adsorption process, can be attributed to non-covalentbonds such as van der Waals forces. The resonance frequency of these bondsfalls in the terahertz (THz) frequency band. Skeletal vibration of organiclinkers also occurs in this band and seems to be affected by adsorption.Previous studies using DFT calculations suggest that the frequency of open-gatemotion exists at the range of 1 to 2 THz. Thus, gas adsorption onto ZIF-8 canbe observed by monitoring changes in its terahertz transmission spectrum as afunction of gas exposure.
