Nitrogen triiodide decomposition. Animation showing the molecular structure and the breaking and forming of bonds during the explosive decomposition of the contact explosive nitrogen triiodide (NI3). The sensitivity of this explosive is due to the immense strain in the molecule, in which three large iodine atoms (purple) are bound to a small nitrogen atom (dark blue). The slightest touch can cause the breakdown of the NI3 molecules, leading to the production of nitrogen gas (N2) and a cloud of iodine vapour (I2). This is shown here as a feather-light touch triggering the decomposition. Single bonds form in the iodine molecule, while triple bonds form in the nitrogen molecules.
