Mössbauer Study of Iron Iodide Produced by a Reaction of Laser-Evaporated Iron Atoms and Methyl Iodide

Abstract

The reaction products of laser-evaporated iron atoms and methyl iodide CH₃I are isolated in low-temperature Ar matrices and their Mössbauer spectra are obtained. The yields of the products vary depending on the concentration of CH₃I in the Ar matrix-gas. The Mössbauer parameters suggest that these species that are isolated in matrices are monomeric FeI₂ and dimeric Fe₂I₄, which is confirmed by molecular orbital calculations.
