Abstract :
X-ray absorption near edge structure (XANES) spectra have been collected for 1-alkyl-3-methylimidazolium bromide [Cnmim]Br ILs with different alkyl chains (n = 2, 4). The XANES technique has been found to be sensitive to the subtle differences in the Br− coordination environment present in [C2mim]Br and [C4mim]Br ILs, that are solid at room temperature. With this Letter we show that XANES is a new effective tool for studying the local structural arrangements around selected atoms in ILs both in the solid and liquid phase.
