Conformational Equilibrium of Bis(trifluoromethanesulfonyl) Imide Anion of a Room-Temperature Ionic Liquid: Raman Spectroscopic Study and DFT Calculations
Kenta Fujii,Takao Fujimori,Toshiyuki Takamuku,Ryo Kanzaki,Yasuhiro Umebayashi,Shin-ichi Ishiguro +5 more
TL;DR: It is concluded that a conformational equilibrium is established between the C1 and C2 conformers of TFSI- in the liquid EMI+TFSI-, and the C2 conformer is more favorable than the C 1 one.
Journal ArticleDOI
Lithium Ion Solvation in Room-Temperature Ionic Liquids Involving Bis(trifluoromethanesulfonyl) Imide Anion Studied by Raman Spectroscopy and DFT Calculations
Yasuhiro Umebayashi,Takushi Mitsugi,Shuhei Fukuda,Takao Fujimori,Kenta Fujii,Ryo Kanzaki,Munetaka Takeuchi,Shin-ichi Ishiguro +7 more
TL;DR: The solvation structure of the lithium ion in room-temperature ionic liquids 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl) imide and BMP(+0TFSI(-)) has been studied by Raman spectroscopy and DFT calculations and it is concluded that the C(1) conformer is more preferred to the C-2 conformer in the vicinity of the Lithium ion.

Evidence of Conformational Equilibrium of 1-Ethyl-3-methylimidazolium in Its Ionic Liquid Salts: Raman Spectroscopic Study and Quantum Chemical Calculations
Yasuhiro Umebayashi,Takao Fujimori,Tetsuya Sukizaki,Mitsunori Asada,Kenta Fujii,Ryo Kanzaki,Shin-ichi Ishiguro +6 more
TL;DR: The enthalpy for conformational change from nonplanar to planar EMI+ experimentally obtained by analyzing band intensities of the conformers at varying temperatures is practically the same as that evaluated by theoretical calculations.
Journal ArticleDOI
Liquid Structure of Room-Temperature Ionic Liquid, 1-Ethyl-3-methylimidazolium Bis-(trifluoromethanesulfonyl) Imide
Kenta Fujii,Yasufumi Soejima,Yasuhiro Kyoshoin,Shuhei Fukuda,Ryo Kanzaki,Yasuhiro Umebayashi,Toshio Yamaguchi,Shin-ichi Ishiguro,Toshiyuki Takamuku +8 more
TL;DR: It is shown that the liquid structure of 1-ethyl-3-methylimidazolium bis-(trifluoromethanesulfonyl) imide is significantly different from the layered crystal structure that involves only the nonplanar staggered EMI(+) and C(1) TFSI(-) conformers.
Journal ArticleDOI
Experimental evidences for molecular origin of low-Q peak in neutron/x-ray scattering of 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ionic liquids
Kenta Fujii,Ryo Kanzaki,Toshiyuki Takamuku,Yasuo Kameda,Shinji Kohara,Mitsuhiro Kanakubo,Mitsuhiro Shibayama,Shin-ichi Ishiguro,Yasuhiro Umebayashi +8 more
TL;DR: A new function; x-ray structure factor intensity at a given Q as a function of r, S(Q) (peak)(r) is introduced, suggesting that the observed low-Q peak intensity depending on n is originated from liquid structures at two r-region of 5-8 and 8-15 Å for all ionic liquids examined except for n = 12.
