The vibrational wavenumbers of crystalline ammonium fluoride were calculated using the density functional method. The results support the experimental conclusions that the symmetric stretching mode in NH 4 F lies at a higher wavenumber than the asymmetric stretch, that these wavenumbers are reversed in ND 4 F and that the librational wavenumbers lie at ∼560 cm –1 .
