Abstract

Raman and infrared spectra of thallous nitrate have been studied in the region 30 to 2000 cm^βˆ’1^ for the temperature interval 80 to 460 K. The bands recorded in TINO~3~ (III) correspond to (Ξ½~i~ + Ξ©__j__) composite transitions where Ξ½~i~ refers to internal and Ξ©__j__ to lattice vibrations. There are two sets of nitrate ions in the unit cell because of the observed splitting of the internal bands of the NO group and also the doubling of some bands due to lattice vibrations.

The interdiffusion coefficient of thallous ion in molten lithium nitrate has heen measured by wave-front-shearing interferometry. The results are obtained in a region of low Tl+ concentration and can be summarized with an Arrhenius equation D = (3.95 & 1.14) x IO-' exp{-(6780 & 330)/RT}, (262-354"C)
