弱弱的问什么是“离子序列”
弱弱的问什么是“离子序列”，请高手详细解释一下。 对应的英语表述是什么？ chaotropic salt [url]http://www.wiki.cn/wiki/Chaotropic_agent[/url] 专业不一样 读得不太懂 LZ参考吧A Chaotropic agent is an agent which causes molecular structure to be disrupted; in particular, those formed by noncovalent forces such as hydrogen bonding, Van der Waals interactions, and the hydrophobic effect. Often structural features, as detected by means such as circular dichroism can be titrated in a chaotrope concentration-dependent fashion.
The most commonly used chaotropes are 6~8M urea and 6M guanidinium chloride, with urea being an uncharged molecule and guanidinium chloride being a hydrochloride salt.
High generic salts can have chaotropic properties, by shielding charges and preventing the stabilization of salt bridges. Hydrogen bonding is stronger in nonpolar media, so salts, which increase the dipole moment of the solvent, can also destabilize hydrogen bonding.
