摘要：

In-beam Mössbauer spectroscopy of 57Fe using a short-lived 57Mn (T1/2 = 89 s) implantation was applied to study the chemical products of localized Fe atoms in ethylene and acetylene matrices at low temperatures. The spectra obtained in both matrices were analyzed as three doublets. In ethylene at 14 K, Fe(C2H4)2 (Fe0, S = 1), [Fe(C2H4)3]+ (Fe+, S = 3/2), and [Fe(C2H4)2]+ (Fe+, S = 3/2) were assigned as derived from the Mössbauer parameters and density functional theory calculations. On the other hand, the products of [Fe(C2H2)2]+ (Fe+, S = 3/2) and [(C2H2)FeCCH2]+ (Fe+, S = 3/2) were determined in the acetylene matrix at 17 K. © 2018, Springer International Publishing AG, part of Springer Nature.
