摘要: Raman spectra of carefully purified (n-C4H9)4N+ AuI2− (TBA-AuI2) were measured between 89 K and room temperature. The bands observed around 110 cm−1 in one the previously reported are ascribed to I3− impurity. Spectra TBA-AuI2 TBA-I3 compared, principal assigned. resonance effect makes its prominent impure samples. crystal symmetries above two salts at low temperature briefly discussed.
