利用短寿命57 Mn（T1/2= 89 s）离子注入57 Fe的在束穆斯堡尔谱研究了低温下Fe原子在乙烯和乙炔基体中的化学产物。在两种基质中获得的光谱作为三个双峰进行分析。在14 K的乙烯中，Fe（C2 H4）2（Fe 0，S= 1），[Fe（C2 H4）3]+（Fe+，S= 3/2）和[Fe（C2 H4）2]+（Fe+，S= 3/2）被指定为来自穆斯堡尔参数和密度泛函理论计算。另一方面，在17 K时，在乙炔基体中测定了[Fe（C2 H2）2]+（Fe+，S= 3/2）和[（C2 H2）FeCCH 2]+（Fe+，S= 3/2）的产物。
In-beam Mössbauer spectroscopy of57Fe using a short-lived57Mn (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.
