Abstract

The Room Temperature Reflectivity of MnF2 Has Been Measured in the Far I.r. between 50 and 800 Cm-1. the Reflectivity Spectra Show Four I.r.-Active Modes Which Can Be Identified as Eu and A2u Modes. the Spectra Also Show Structure Which Might Be Related to Multiphonon Effects. the Dielectric Functions Were Determined by Fitting the Reflectivity Data with Classical Oscillator Parameters. © 1974.
