atoms or ions produces copious amounts of cluster ions, among which M+(H2O)n and/or M+OH(H2O)n frequently dominate. Variable-energy collision-induced dissociation of these ions in a triple quadrupole mass spectrometer yields the successive gas-phase solvation energies. Several known hydration and bond energies have been reproduced, and the first and second hydration energies of the Cu+ ion have been
低温溅射金属盐、水合结晶过渡金属盐、磨砂金属表面和具有千电子伏能量稀有气体原子或离子的磨砂金属盐的冷冻水溶液,产生大量簇离子,其中 M+(H2O )n 和/或 M+OH(H2O)n 经常占主导地位。这些离子在三重四极杆质谱仪中的可变能量碰撞诱导解离产生连续的气相溶剂化能量。几个已知的水合能和键能已被重现,Cu+ 离子的第一和第二水合能分别确定为 35 ± 3 和 39 ± 3 kcal/mol。得出的结论是气态 Cu+ 更喜欢双配位。
