本文采用盆跳跃搜索算法结合量子化学计算研究了离子水团簇(H_2O)_n ~+(n= 3-9)的结构和成键。最初的候选人低能量异构体产生的盆地跳跃结合密度泛函理论。随后,结构和能量分别采用二阶Møller-Plesset微扰理论和耦合集团理论进行了修正。最低能量的异构体被发现涉及质子转移,以得到H3 O+和OH自由基,这是更稳定的比异构体含有半键合肼类片段(H2O-OH 2),与计算的红外光谱与实验数据一致。对于(H2O)9+观察到一个新的结构基序,包括质子转移形成H3 O+和OH,但与参与半键合到另一个水分子的OH自由基进行了讨论。
The structure and bonding in ionized water clusters, (H2O)n+(n= 3–9), has been studied using the basin hopping search algorithm in combination with quantum chemical calculations. Initially candidate low energy isomers were generated using basin hopping in conjunction with density functional theory. Subsequently, the structures and energies were refined using second order Møller–Plesset perturbation theory and coupled cluster theory, respectively. The lowest energy isomers are found to involve proton transfer to give H3O+and a OH radical, which are more stable than isomers containing the hemibonded hydrazine-like fragment (H2O–OH2), with the calculated infrared spectra consistent with experimental data. For (H2O)9+the observation of a new structural motif comprising proton transfer to form H3O+and OH, but with the OH radical involved in hemibonding to another water molecule is discussed.
