Fourier-transformed Infrared (FTIR) spectra were taken using Alpha Bruker FTIR spectrometer inside of the same glovebox. Spectra were recorded in attenuated total reflectance (ATR) configuration using diamond crystal. Background and sample absorbance spectra were measured in the 400 to 4000 cm -1 wavenumber interval with a resolution of 2cm -1 and 100 scans.
