Abstract
The vibrational spectra of NaOX (X = H or D) at room temperature and 77 K are reported. A normal coβordinate analysis has been carried out to assign the observed bands on the basis of the valence force field. The force constants were adjusted by considering a bond distance and reproduce well the observed frequencies. In the dispersion relations on k~2~ and k~x~ the librational modes were found to be insensitive to k, whereas the translational modes except for the A~1g~ and B~1u~ modes vary considerably with k. Some bands were assigned to the combination band between a fundamental and an acoustic mode.
