Abstract
The vibration modes of crystal NENP [Ni(C2H8N2)2NO2ClO4] in the wavenu mber range of 50-500 cm-1 are studied by the infrared reflection spect ra. The dielectric function property of the sample is obtained by the Kramers-Kronig calculation on the reflection spectra. The dielectric f unction polarization property induced by the vibration mode polarizati on in far infrared region is investigated.
