The dimer yields in the radiolysis of the neo-C5H12-cyclo-C5H10 (1 mol%) mixtures at 77 and 4 K have been measured by capillary gas chromatography. Analysis of the results indicates that cyclopentyl radicals are produced selectively at 77 K, while their selective formation is suppressed at 4 K. This result coincides well with the data obtained by ESR spectroscopy.
新-C5H12-环-C5H10 (1 mol%) 混合物在 77 和 4 K 的辐射分解中的二聚体产率已通过毛细管气相色谱法测量。结果分析表明,环戊基自由基在 77 K 下选择性产生,而它们的选择性形成在 4 K 下被抑制。该结果与 ESR 光谱获得的数据非常吻合。
