An experimental and computational study of the ion-molecule reactions initiated by the reaction of SC 2 H 4 .+ with SC 2 H 4 has been carried out. The dimer ion is observed in a hybrid drift tube/ion source under chemical ionization conditions at low temperatures and high pressures. However, the ion intensity is much lower than expected for a product containing a stable two-center three-electron (2c-3e)
对由 SC 2 H 4 .+ 与 SC 2 H 4 反应引发的离子-分子反应进行了实验和计算研究。在低温和高压的化学电离条件下,在混合漂移管/离子源中观察到二聚体离子。然而,对于含有稳定的双中心三电子 (2c-3e) S. 的产物,离子强度远低于预期。.S 债券。高于室温,m/z 92 S 2 C 2 H 4 .+ 、m/z 124 S 3 C 2 H 4 .+ 、m/z 156 S 4 C 2 H 4 .+ 和 m/z 的离子强度184 S 4 C 4 H 8 .+
