Abstract

Infrared and Raman spectra for (K⁺) (CF₃BF₃⁻) have been obtained from 4000 to 50 cm⁻¹. Spectral assignments were made on the basis of C_3v symmetry using both ¹⁰B and ¹¹B compounds. In addition, a normal coordinate analysis was performed to obtain the potential energy distribution of the normal modes. A Urey-Bradley type force field was used, and force constants obtained for the CF₃ and BF₃ groupings were compared to those in C₂F₆ and BF₄⁻.
