Dalgic, S.Caliskan, M.2024-06-122024-06-1220091454-41641841-7132https://hdl.handle.net/20.500.14551/24709In this work, the molecular geometries and vibrational frequencies of selected rare-earth trichlorides (YCl3, CeCl3, DyCl3) and their dimerics were computed using the interionic force model. In order to the determine of the model parameters, we have fitted the measurement value of the breathing mode of molecular dimerics in molecular structure calculations. It has been indicated that the ground state structures of monomeric rare-earth thrichlorides have D-3h symmetry and their dimerics have D-2h symmetry. The results for the equilibrium bond lengths, bond angles and vibrational frequencies are compared with the measured values obtained from electron diffraction and with the results of other theoretical calculations. The agreement can be considered as very reasonable.eninfo:eu-repo/semantics/closedAccessYttriumCerium And Dysprosium TrichloridesInterionic Force ModelVibrational FrequenciesLanthanide TrihalidesEquilibrium StructureElectron-DiffractionMetal-HalidesModelVibrationsAluminumArticle115618624Q4WOS:0002672126000132-s2.0-76049103375Q4
