• Effects of' an itatpurity on a displacive phase transition are exa?tained for crystalline biphenyl(BP) by adiabatic calorimetry. While the azaotaaaly iza the heat capacity remained trnchangedby 1% of naphthalene (NAP, the anon?aly disappeared at 1% of' 4,4'-difltrorobiphenyl (DFBP).The obsex'ved effect is disctrssed in relation to the localizattion of' the sof't-taaode. Two itnpuritiesdiffer in the existence/absence of' the txvisting degree of' f'reedorta that prodtuces the soft-ttaode.The DFBP uaaolecule weakly localizes the lattice vibrartion of' BP crystal over the wide rangeof distance. The localization by the NA rnolectrle is strong and only the close neighboring BPrnolecules are affected.
