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

摘要

I. Bismuth trifluoride was prepared as a precipitate from the addition ofpotassium trifluoride to a solution of bismuth nitrate dissolved in nitricacid. Infrared spectra of Nujol mulls and cesium bromide pellets containingbismuth 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. Dueto equipment limitations, it was not possible to go further out in the infraredrange below thirty-eight microns to obtain the other two absorptionbands.
