报告内容简介：

Ionic & molecular (including hydrated) clusters with molecular specificity, selected sizes, and controlled compositions are ideal model systems to understand condensed phases processes and obtain molecular-level understanding of environmental materials and solution chemistry. In this talk, I will present our recent research progress on a few topics including (1) ion specific interactions between alkali cations and dicarboxylate dianions; (2) stepwise hydration on a few environmentally important anions; (3) Intrinsic electronic structures of diradical species, and (4) gaseous organometallic species important to homogeneous catalysis.
