Raman and infrared study of the crystals with molecular anions in the region of a solid-liquid phase transition.
It is presented the Raman and infrared (IR) spectroscopic investigations of the thiocyanates: LiSCN, NaSCN, KSCN, RbSCN, CsSCN; nitrates: Ca(NO3)2, Sr(NO3)2, Ba(NO3)2, Pb(NO3)2; and perrhenates: LiReO4, NaReO4, KReO4 in the region of a solid-liquid phase transition. The differences in a pre-melting behavior of this salts were found which can be attributed to a different geometry of the SCN-, NO3- and ReO4- anions.
