Surface characterization of 1-butyl-3-methylimidazolium Br(super -), I(super -), PF(sub 6)(super -), BF(sub 4)(super -), [CF(sub 3)SO(sub 2)](sub 2)N(super -), SCN(super -), CH(sub 3)SO(sub 3)(super -), SH(sub 3)SO(sub 4)(super -), and (CN(sub 2))N(super -) ionic liquids by sum frequency generation
Article Abstract:
Sum frequency generation spectroscopy (SFG) is used for the surface characterization at the gas-liquid interface of the 1-butyl-3-methylimidazolium cation combined with Br(super -), I(super -), PF(sub 6)(super -), BF(sub 4)(super -), (CF(sub 3)SO(sub 2))(sub 2)N(super -), SCN(super -), CH(sub 3)SO(sub 3)(super -), SH(sub 3)SO(sub 4)(super -), and [CN(sub 2)]N(super -) (DCN) anions. The analysis of the polarization-dependent SFG spectra has provided a reliable characterization of the cation at the liquid-gas interface.

Sum frequency generation study of the room-temperature ionic liquids/quartz interface
Article Abstract:
Sum frequency generation vibrational spectroscopy was used to characterize the interfacial properties of two ionic liquids as well as 1-methylimidazole and 1-butylimidazole on a quartz surface and Raman spectroscopy was used to identify vibrations and conclude whether they were symmetric or asymmetric. It was concluded that larger the anion the more the imidazolium ring was tilted towards normal.

Influence of water on the surface of the water-miscible ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate: A sum frequency generation analysis
Article Abstract:
Sum frequency generation spectroscopy is used to study the influence of water on the surface of the water-miscible ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4]. The results suggest that water has no drastic effect on the surface orientation of [BMIM][BF4] cation for concentrations from 0.0002[X.sub.IL] to 1[X.sub.IL].
