| Abstract: | Laser-ablated iron atoms and fine particles were isolated in low-temperature Ar matrices, and their chemistry was studied by means of Mössbauer spectroscopy. Reaction of Fe with O2 produces Fe-O, O-Fe-O, and Fe-O2 as isolated in Ar matrices. On annealing the sample, unstable species are converted to more stable species in the matrix. Similarly, Fe-O and O-Fe-O were obtained from the reaction of iron atoms with N2O. Furthermore, Fe-N was found to be produced by the reactions of laser-ablated Fe with N2. |
