The elastic constantsC₁₁,C₁₂ andC₄₄ of sodium chlorate single crystal have been evaluated using 10 MHz ultrasonic pulse echo superposition technique. The values areC₁₁=4.90,C₁₂=1.39,C₄₄=1.17 (× 10¹⁰N/m²) at 298 K and 6.15, 2.16, 1.32 (×10¹⁰N/m²) at 77 K. The data agree well with the values measured earlier up to 223 K. Brief mention is also made of the low temperature bonding problems in these soft crystals.

Quantum chemical calculations have been employed to study the molecular effects produced by $\rm{Cr_{2}O_{3}/SnO_{2}}$ optimised structure. The theoretical parameters of the transparent conducting metal oxides were calculated using DFT/B3LYP/LANL2DZ method. The optimised bond parameters such as bond lengths, bond angles and dihedral angles were calculated using the same theory. The non-linear optical property of the title compound was calculated using first-order hyperpolarisability calculation. The calculated HOMO–LUMO analysis explains the charge transfer interaction between the molecule. In addition, MEP and Mulliken atomic charges werealso calculated and analysed.
