Enrichment of Germanium-73 with the Magnetic Isotope Effect on the Hydrogen Abstraction Reaction of Triplet Benzophenone with Triethylgermane in an SDS Micellar Solution
Using the hydrogenabstraction reaction of triplet benzophenone with triethylgermane in an SDS micellar solution, we succeeded in enriching 73Ge with the magnetic isotope effect. At zero magnetic field, 0.5% enrichment of 73Ge was observed for the cage product (diphenyl(triethylgermyl)methanol). With increasing magnetic field strength (B), the enrichment of 73Ge increased initially, attaining the maximum
利用三线态二苯甲酮与三乙基锗烷在 SDS 胶束溶液中的夺氢反应,我们成功地利用磁性同位素效应富集了 73Ge。在零磁场下,观察到笼状产物(二苯基(三乙基锗基)甲醇)的 73Ge 富集率为 0.5%。随着磁场强度(B)的增加,73Ge的富集最初增加,在500 G时达到最大值5.3%。在更高的磁场(500 G < B ≤ 10 kG)下,它逐渐减少,在10 kG时变为1.0% . 73Ge 富集的磁场依赖性可以通过弛豫机制来解释。
