摘要：

Raman spectra are reported for NH4Br and NH4I from 86 to 295 K under hydrostatic pressures from 1 bar to 7 kbar. Phases II, III, and IV were studied. The pressure dependence is reported for the lattice modes, for the librational mode and its harmonics, and for certain combination bands. Several theoretical models for the librational potential are discussed and compared with the data. © 1979 American Institute of Physics.
