用红外-可见和频振动光谱研究了1-丁基-3-甲基咪唑与四氟硼酸盐和六氟磷盐在气液界面上的离子取向。定量分析表明，对于这两种盐，丁基链的末端甲基是极性取向的，其对称轴几乎垂直于表面。(C)2004爱思唯尔B.V.保留所有权利。
Orientation of cations at the air/liquid interfaces of the salts of 1-butyl-3-methyl imidazolium with tetrafluoroborate and hexafluorophosphate is studied using infrared-visible sum frequency vibrational spectroscopy. For both salts, quantitative analyses show that the terminal methyl group of the butyl chain is polar-oriented with its symmetry axis aligned nearly vertical to the surface. (C) 2004 Elsevier B.V.
