Fluorine azide

Fluorine azide can be made by reacting hydrazoic acid or sodium azide, with fluorine gas. : : Fluorine azide decomposes without explosion at normal temperatures to make dinitrogen difluoride: :. Due to the explosion hazard, only very small quantities of this substance should be handled at a time. ==Properties==

Spectroscopy Shape Distances between atoms are F–N 0.1444 nm, FN=NN 0.1253 nm and FNN=N 0.1132 nm. Physical adsorbs on to solid surfaces of potassium fluoride, but not onto lithium fluoride or sodium fluoride. This property was being investigated so that could boost the energy of solid propellants. The ultraviolet photoelectric spectrum shows ionisation peaks at 11.01, 13,72, 15.6, 15.9, 16.67, 18.2, and 19.7 eV. Respectively these are assigned to the orbitals: π, nN or nF, nF, πF, nN or σ, π and σ. ==References==
