The vibrational spectra of NaOX (X = H or D) at room temperature and 77 K are reported. A normal co‐ordinate 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.
