采用短寿命57mn （T1/2=1.45 m）束流Mössbauer光谱法研究了在低浓度乙烯基质中分离的单铁原子的反应产物。用四组分分析了16k时乙烯-氩气基体中57mn生成57fe的束内Mössbauer光谱。通过密度泛函理论计算来确定分配。结果表明，该反应生成了自旋态为S = 2的单铁态Fe（C2H4）。
The reaction products of isolated single iron atoms in a low concentration matrix of ethylene were studied using in-beam Mössbauer spectroscopy with a short-lived57Mn (T1/2=1.45 m) beam. The in-beam Mössbauer spectrum of57Fe arising from57Mn in a matrix of ethylene and argon measured at 16 K was analyzed with four components. Density functional theory calculations were carried out to confirm the assignments. It was suggested that the reaction produced monoiron species of Fe(C2H4) with a spin state of S = 2.
