PERSISTENT INFRARED HOLE-BURNING OF AMMONIUM STEARATE

Preliminary analysis of the X-ray diffraction of single crystals provi des the unit cell parameters and suggests standard B-type packing of t he polymethylene chains. Spectral hole burning of the N-D stretching b ands of ammonium stearate, doped with some deuterium, produces holes a nd antiholes in three regions of the spectrum. The three regions conta in the stretching bands, the NH3 rocking bands, and the rocking-librat ion bands, respectively. The holes and antiholes identify the vibratio nal bands and correlate them with the different possible orientations of the NH3D+ in the crystal.
