✦ Synopsis

Enthalpy chanQa8 of tha cryatal-plaatic and plastic-liquid tranaitiona arm ralatad to the tamparatura ranga of atability of tha plastic phaaa. Tharnodynarica of tha plastic atata of binary mixture8 hava baan axaminad. Infrared corralation tinaa, t, , and activation anarQiaa hava baan aaaaurad for a Ceu molaculaa in tha plastic stat@. Rolacular tumbling timaa,~t, hava also baan naaaurad l mployinQ LSR spectra of a apin-probe. Plot8 of lop T,(r,) veraa l/T are continuous through tha plastic-liquid tranaition. Activation anorQiaa for molecular motion aaam to vary in tha mama direction am tha AH of tha plaatic-cryatal transition. Intrarad corralation timaa of aoluta aolaculaa in binary l olutiona in tha plastic and the liquid atataa l hou intaraatinp variationa uith aoluta concantration. * Communication No. 107 * To uhon all corraapondanca l hould ba addraaaad.
