Infrared spectra of bismuth trifluoride and chlorodiborane: attempted preparation of bismuth hydride for infrared study

Abstract

I. Bismuth trifluoride was prepared as a precipitate from the addition of potassium trifluoride to a solution of bismuth nitrate dissolved in nitric acid. Infrared spectra of Nujol mulls and cesium bromide pellets containing bismuth trifluoride gave only tvo of the four absorption bands expected. One band was at £23 and the other a broad band at 2£8 wave numbers. Due to equipment limitations, it was not possible to go further out in the infrared range below thirty-eight microns to obtain the other two absorption bands.
