Pm3 Method

The standard heat of formation (ΔHof) and binding energy (ΔEb) for the free compound and their derivatives are calculated by using the PM3 method at 273K of Hyperchem.-8.07 program. The compound is more stable than their derivatives. furthermore to investigate the reactive site of the molecules the electrostatic potential of free derivatives is measured and pm3 is used to evaluate the vibrational spectra of the free derivatives, the frequencies are obtained approximately agreed with those values experimentally found; in addition, the calculation helps to assign clearly the most diagnostic bands .

Bromine Trifluoride

The barium fluorobromate(III) was obtained as the product of interaction between barium fluoride and bromine(III) trifluoride. The heat of formation of Ba(BrF4)2 was found by isothermal calorimetry method. By the TG/DT analysis the thermal stability of Ba(BrF4)2 was researched. It was found that this compound is mostly stable in the atmosphere or argon up to 250 °C. It was shown that bromine trifluoride and its derive compounds with alkali and alkali-earth metals fluorides can be applied like a highly-active brominating agent in case of production of various composite materials based on polyhalogenated aromatics.
