Abstract
Extensive high-resolution vibrational density of slates measurements h ave been performed on ordered niobium hydrides and deuterides by means of neutron vibrational spectroscopy (NVS). The investigations show a splitting of the hydrogen vibrational modes into a two-peak system in the case of the epsilon-phase and a three-peak system in the case of t he lambda-phase. These different peak systems can be assigned to diffe rent hydrogen sites, which is further confirmed by neutron diffraction (ND) data.
