Abstract

Water clusters (H(2)O)(n), n<or=16, are produced by supersonic expansion of water vapor into vacuum, and then pick up a DCl molecule. The resulting mixed clusters are analyzed by electron bombardment ionization mass spectrometry. In all cases observed, the chlorine atom is lost in the ionization process, producing a deuterated water cluster cation [(H(2)O)(n)D(+)]. This suggests that the chlorine atom stays on the surface and has a weaker bond to the host cluster.

摘要

通过将水蒸气超声速膨胀到真空中产生水团簇(H₂O)ₙ，n≤16，然后捕获一个DCl分子。通过电子轰击电离质谱对所得的混合团簇进行分析。在所有观察到的情况中，氯原子在电离过程中丢失，产生一个氘代水团簇阳离子[(H₂O)ₙD⁺]。这表明氯原子留在表面，并且与主体团簇的键较弱。
