Abstract
The infrared spectrum of single crystals of brucite [Mg(OH)2] has been examined under high resolving power between 2 and 3μ. It contains at least 16 bands most of which are shown to be OH stretching frequencies and which exhibit a variety of polarization properties. It follows that the unit cell of brucite must be much larger than had been previously assumed and that the positions of the hydrogen atoms have been incorrectly assigned from x-ray data.
