特定的离子效应，代表近普遍的霍夫迈斯特现象，在三个不同的系统中说明。这些是从环糊精，L-丝氨酸的旋光度，和两种微生物（金黄色葡萄球菌和铜绿假单胞菌）的生长速率的超分子组装体的形成。强的特定离子效应可以与阴离子极化率和相关的物理化学参数相关联。结果表明，在这些现象中的色散（非静电）力的相关性。(c)2006年由Elsevier B. V.出版
Specific ion effects, representative of near-universal Hofmeister phenomena, are illustrated in three different systems. These are the formation of supramolecular assemblies from cyclodextrins, the optical rotation of L-serine, and the growth rate of two kinds of microorganisms (Staphylococcus aureus and Pseudomonas aeruginosa). The strong specific ion effects can be correlated with the anion polarizabilities and related physico-chemical parameters. The results show the relevance of dispersion (non-electrostatic) forces in these phenomena. (c) 2006 Published by Elsevier B.V.
