摘要：

The pressure dependence of the tunneling and librational modes of the coupled methyl groups in lithium acetate dihydrate was studied by inelastic neutron scattering at liquid helium temperatures and the results compared with detailed model calculations. An increase of both the single particle and coupling potential parameters with increasing pressure was observed. © 1987 Springer-Verlag.
