The low-temperature heat capacity of Tris-dimethylaminoarsine

The temperature dependence of the heat capacity of tris-dimethylaminoarsine was studied in the temperature range 5-300 K. The temperature, enthalpy, and entropy of fusion were determined. The thermodynamic functions of tris-dimethylaminoarsine in the temperature range of measurements and the thermodynamic functions of formation of the compound at 298.15 K were calculated.
