A simple potential function is used to fit the observed fundamentals and overtones of the asymmetric and symmetric stretching frequencies of the bifluoride ion in KHF2 and KDF2 and also to account for the difference in mean FHF and FDF bond lengths. The agreement with experiment is good, considering the simplicity of the function and the uncertainties in the data. This potential function is based on a linear symmetric model for the bifluoride ion and there is thus no spectroscopic evidence in favor of an asymmetric model.
