Abstract The vibration modes of crystal NENP [Ni(C2H8N2)2NO2 ClO4] in the wavenumber range of 50-5000cm-1 are studied by the infrared reflection spectra The dielectric function property of the sample is obtained by the Kramers-Kroning calculation on the reflection spectra. The dielectric function polarization property induced by the vibration mode polarization in far infrared region is investigated.
