摘要：

A combination of inelastic neutron scattering (INS) spectroscopy and Raman spectroscopy with periodic density functional theory calculations is used to provide a complete assignment of the vibrational spectra of alpha-lithium amidoborane (alpha-LiNH2BH3). The Born charge density and the atomic motion up to the decomposition temperature have been modelled. These models not only explain the nature of bonding in alpha-LiNH2BH3 but also provide an insight into the atomic mechanisms of its decomposition. The (INS) measurements were performed in the range of 0-4000 cm(-1) on the high-resolution time-of-flight TOSCA INS spectrometer at the ISIS Spallation Neutron Source at the Rutherford Appleton Laboratory.
