The structural dynamics of Li(NH3)4, the lowest melting point metal, are reported in the range of phonon and low-energy internal distortions. Hindrance of NH3libration in the solid are characterisedviainelastic neutron scattering and computational modeling.

and Li or K atoms in solidargon led to the spontaneous formation of numerous products classified in three groups. The first group is constituted by mononuclear species M(NH3)n mainly characterized by the strongly intensity enhanced ν1 (A1 stretching) and ν2 (A1 bending) modes of ammonia. For M=Li and n=1, 6Li/7Li and H/D, isotopic substitution allows complete assisgnment of the spectrum and force
