Discovering a new type of reaction with simple molecules is not an everyday occurrence : The isomers 2 , which are formed upon matrix irradiation of the haloiodomethane 1 , can be regarded as unsolvated contact ion pairs. In this rearrangement, the iodine atom migrates from the carbon atom to the halogen atom. The isomers 2a (violet), 2b (green) and 2c (yellow) can be reconverted into the educts by changing the wavelength of the radiated light (a, b, c: XI, Br, Cl).
