This compound is used as an animal repellent and also as an insecticide or fungicide (Stewart, 1951). It is also a starting material for the preparation of other compounds (Baluja et al, 1960;Morrison et al, 1953;Stewart, 1951), an accelerator and activator for rubber vulcanization (Mathes et al, 1955) and an accelerator for the curing of polyepoxide-polyimine materials (Goel, 1988).…”

Analysis of the Crystal Structure and Optical Spectra of Stoichiometric SmOF

“…The IR-active vibrations involved were confirmed by the IR spectra of pure SmOF. , Lines corresponding to the frequencies 130, 230, and 300 cm -1 were usually found. The vibronic transitions observed were mainly due to the coupling with the RE−O vibrations because of the increasing polarizability and covalency of the ligand from F - to O 2- , but coupling with the RE−F vibrations could not be excluded either. Moreover, the line shapes and analysis of the line intensities as a function of a temperature supported the identification of the vibronic lines.…”
