摘要

The 125Te Mössbauer spectra for (CF3) 2Te and (C6F5) 2Te have been recorded and exhibit significantly larger quadrupole splittings (14.02 and 13.40 mm s-1 respectively) than those of Me2Te (10.5 mm s-1) and Ph2Te (11.0 mm s-1). The dihalides (CF3) 2TeX2 and (C66F5) 2TeX2 (X= F, Cl, Br) have consistently smaller quadrupole splittings than the dihalides Me2Tex2 and Ph2TeX2. These observations are consistent with the greater ...
