The solvation structures ofN-butyl-N-methylpyrrolidinium dicyanamide ([BMP][DCA]) surrounding silver ions were investigated using attenuated total reflectance-ultraviolet (ATR-UV) spectroscopy. The addition of Ag+to [BMP][DCA] red-shifted the [DCA]−absorption band. The shift direction was opposite to that caused by the addition of Li+, and these spectral shifts were qualitatively reproduced using quantum chemical calculations. Multivariate analysis (the multivariate curve resolution-alternating least squares; MCR-ALS) and molecular dynamics simulations were used to decompose the ATR-UV spectra into separate [DCA]−and Ag-solvated [DCA]−spectra. Both multivariate analysis and molecular dynamics simulation showed that the coordination number of [DCA]−around Ag+was approximately-five. The proposed method using spectroscopic techniques, spectral decomposition, and simulations can be used for the quantitative investigation of various solvation structures, which are fundamental features in electrochemistry.
