Understanding the interplay between these two subsystems is a challenging problem, but it is this coupling that is widely conjectured to be responsible for the unique behavior of photocarriers in these materials. In this work, we use the fact that the polarizability of the organic cation strongly depends on the ambient electrostatic environment to put the molecule forward as a sensitive probe of the local crystal fields inside the lattice cell. We measure the average polarizability of the C/N–H bond stretching mode by means of infrared spectroscopy, which allows us to deduce the character of the motion of the cation molecule, find the magnitude of the local crystal field, and place an estimate on the strength of the hydrogen bond between the hydrogen and halide atoms. Our results pave the way for understanding electric fields in lead-halide perovskites using infrared bond spectroscopy.","lang":"eng"}],"type":"journal_article","file":[{"date_updated":"2023-07-19T06:55:39Z","file_id":"13253","success":1,"date_created":"2023-07-19T06:55:39Z","file_size":2121252,"relation":"main_file","checksum":"c0c040063f06a51b9c463adc504f1a23","content_type":"application/pdf","file_name":"2023_JourPhysChemistry_Wei.pdf","access_level":"open_access","creator":"dernst"}],"day":"05","month":"07","article_processing_charge":"Yes (via OA deal)","date_updated":"2023-07-19T06:59:19Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"title":"Bond polarizability as a probe of local crystal fields in hybrid lead-halide perovskites","quality_controlled":"1","status":"public","oa_version":"Published Version","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2023-07-18T11:13:17Z","publisher":"American Chemical Society","article_type":"original","citation":{"ama":"Wei Y, Volosniev A, Lorenc D, et al.
