	Nitrogen triiodide. The study and stabilisation of an explosive
		Nitrogen triiodide, is under normal atmospheric pressures and temperatures, a contact explosive.
		The infra red scan was performed using the nitrogen triiodide trapped in an agar made up with 0.880 S.G. ammonia and left for 24 hours to set.
		Nitrogen triiodide has a dark colour, so there should be a wavelength for maximum absorbance.

	Nitrogen triiodide - Wikipedia, the free encyclopedia
		Nitrogen triiodide is a dark red compound, first characterized by X-ray crystallography in 1990, when it was prepared by an ammonia-free route.
		The material that is usually called "nitrogen triiodide" is prepared by the reaction of iodine with ammonia.
		Nitrogen triiodide is the contact explosive used in Brainiac: Science Abuse, named "Peter Logan's Exploding Paste" on the show, although the details of its production are not mentioned for safety purposes.

	Nitrogen triiodide (via CobWeb/3.1 planet03.csc.ncsu.edu) (Site not responding. Last check: 2007-10-10)
		In chemistry, nitrogen triiodide, also called ammonium triiodide, and sometimes referred to as nitrogen iodide, is a highly explosive compound of nitrogen and iodine, NI Being a contact explosive, small quantities explode with a gunpowder-like snap when touched by even a feather, releasing a volatile cloud of iodine vapor.
		Nitrogen triiodide should be handled with extreme caution, as the dry compound explodes spontaneously.
		Small amounts of Nitrogen triiodide are sometimes synthesized as a demonstration to high school chemistry students.

	Nitrogen triiodide. The study and stabilisation of an explosive
		+ NH Nitrogen triiodide is formed by the reaction between iodine solid and ammonia (0.880 S.G.).
		The structure can be envisaged as a central nitrogen with an iodine atom on each bond, the forth corner comes from the lone pair on the nitrogen.
		This procedure yields only small amounts of the triiodide as only a small surface area of iodine is in contact with the ammonia.

	Nitrogen Tri-iodide - MOTM
		When dry solid nitrogen triiodide is touched, even with a feather, it decomposes rather violently.
		Traditionally, nitrogen triiodide is made by reacting iodine with aqueous ammonia solution.
		In all these compounds, the nitrogen atom has a complete "octet", with four outer-shell electron pairs; one of these is a non-bonding ("lone") pair.

		________________________________________________________________ 1) nitrogen triiodide or carbon disulfide Nitrogen triiodide has a structure identical to ammonia, except that hydrogen is replaced with iodine.

	Contact Explosives
		The reason for this intelligence test is that nitrogen triiodide is a contact explosive: When dry, the slightest disturbance causes it to explode violently.
		Once nitrogen triiodide is dry, it will explode literally at the touch of a feather (here's a video showing exactly that from the Journal of Chemical Education's website).
		If you decide to try anything similar, remember that nitrogen triiodide is not only unbelievably sensitive, the more so the more dry it is, it's also a high explosive.

	Explosion of NI3 (Site not responding. Last check: 2007-10-10)
		When the aqueous ammonia is added to the iodine, a redox reaction occurs, resulting in solid nitrogen triiodide in complex with ammonia, surrounded by aqueous ammonium iodide.
		However, when the moisture evaporates, the nitrogen triiodide becomes unstable, partially due to the large radius of iodine.
		The kinetic energy of the feather or wax paper serves as the activation energy for a rapid and violent decomposition reaction, completely obliterating the nitrogen triiodide (and probably the filter paper) as the atoms reform into diatomic gases, with ammonium iodide residue.

	John Straub's lecture notes
		The molecule is the dimer of two nitrogen dioxide molecules, where the nitrogen atoms have paired their unpaired electrons to form a single nitrogen-nitrogen covalent bond.
		As is the case with ammonia, the nitrogen triiodide molecule has a substantial dipole moment, making the molecule polar.
		When the nitrogen triiodide molecule is solvated in water, the polar water molecules make energetically favorable arrangements with the polar nitrogen triiodide molecule.

	The NI3 Incidents
		To make nitrogen triiodide, one must soak fine iodine crystals in a strong ammonia solution for at least half an hour.
		I felt it was safe to leave the experiment on its own because the book explained that nitrogen triiodide was relatively insensitive while it was wet; it didn't become a contact explosive until it was dry.
		I departed when he mixed it with some sugar and left it to dry with the hope of attracting flies - he had read another reference that described nitrogen triiodide as being “so sensitive that it will be set off by a fly's footsteps”.
