title: Mössbauer study of the reaction of laser-evaporated iron atoms with nitrogen molecules in low-temperature argon matrices.
abstract: Reaction products of laser-evaporated iron atoms with nitrogen molecules were investigated using a low-temperature matrix isolation technique. The products observed in the Mössbauer spectra were FeNNN, Fe(NN), and Fe(NN)2, isolated in argon matrices. Yields of the species changed, depending on the concentration of nitrogen in the matrix. A product assigned to Fe(NN)6 was obtained in a pure nitrogen matrix. Infrared spectra and molecular orbital calculations of the products support these findings.
