Abstract
Vibrational spectra of ammonium iodide NH4I were studied at pressures up to 10 GPa by incoherent inelastic neutron scattering. The pressure dependence s of the frequencies of librational and transverse optical modes suggest th at they are hybridized upon pressure buildup. (C) 2001 MAIK "Nauka/ Interpe riodica".
