Tracking Thermal-Induced Amorphization of a Zeolitic Imidazolate Framework via Synchrotron In Situ Far-Infrared Spectroscopy

We present the first use of in situ far-infrared spectroscopy to analyze the thermal amorphization of a zeolitic imidazolate framework material. We explain the nature of vibrational motion changes during the amorphization process and reveal new insights into the effect that temperature has on the Zn-N tetrahedra.
