Abstract

The molar specific heat of NaBrO~3~ in the temperature range 4.2–336 K was determined experimentally and compared with the theory developed by Stahl and generalized in this paper. The relationship between the molar specific heat and temperature was explicitly studied and compared with results obtained by other workers. The method developed also produces the Debye temperature, Θ the maximum angular frequency, omega;~m~, and the product Iω~t~^2^ of the BrO~3~ group, where I is the moment of inertia and ω~l~, is the lattice vibration. The relationships between the ^79^Br NQR frequency and temperature and between the NQR frequency and molar specific heat were obtained.
