چکیده انگلیسی
Spectral investigations of the new organic metal β-(EDT-DTDSF)4Hg3I8 were performed. Polarized reflectance (from 500 to 17000 cmâ1) and Raman spectra of single crystals were studied at room temperature. An electronic dispersion in IR spectra was analyzed versus temperature (from 4 to 300 K) in terms of the Drude model and optical transport parameters were determined. Additionally, the optical absorption spectra of the powdered salt dispersed in KBr pellets were measured in the 400-45 000 cmâ1 range. The proposed assignment of vibrational features of β-(EDT-DTDSF)4Hg3I8 salt was based on ab initio calculations of the normal modes of EDT-DTDSF0 and EDT-DTDSF+.
