Abstract
Raman spectra of the internal,nodes of ND4+-ion in (ND4)(2)PbCl6 cryst al have bees recorded in the temperature range of 5-300K. A new struct ural Phase transition was observed at 34K because of deuterium effect. Discontinuous behaviours of the internal,nodes of the ND4+-ion at thi s temperature show that the structural transition is one of first orde r.
