Loss of chlorine in mass spectra of DCl picked up by water clusters in a beam.
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.
