使用超高分辨率漂移时间离子迁移谱仪（分辨率 Rp= 235）和环境压力下的紫外电离 (10.6 eV) 测量丙酮和全氘化丙酮 (丙酮-d6) 的混合物，发现三个分离的峰。其中两个峰很容易与丙酮和全氘化丙酮相关。在以前的出版物中，一些发现表明甲基基团的交换和 H3COCD3 相关峰的形成。在这项工作中，使用高分辨率漂移时间离子迁移时间飞行质谱仪对形成的离子种类进行了分析。质谱清楚地显示了三个质子结合二聚体峰的形成，而丙酮和丙酮-d6 之间的峰是由一个丙酮和一个丙酮-d6 分子组成的质子结合混合二聚体。
Measuring a mixture of acetone and perdeuterated acetone (acetone-d6) with an ultra-high resolution drift time ion mobility spectrometer (resolving power of Rp= 235) and ultraviolet ionization (10.6 eV) at ambient pressure reveals three separated peaks. Two of the peaks can easily be associated with acetone and perdeuterated acetone. In a former publication several findings indicated an exchange of a methyl group and the formation of a H3COCD3related peak. In this work the formed ion species were analyzed with a high resolution drift time ion mobility time of flight mass spectrometer. The mass spectra clearly show the formation of three proton-bound dimer peaks whereas the peak between acetone and acetone-d6 is a proton-bound mixed dimer consisting of one acetone and one acetone-d6 molecule.
