Description

<p>Attenuated total reflectance–far ultraviolet (ATR-FUV) spectra of Li+ and polyether ligands, such as glymes and poly (ethylene glycol) (PEG), in solution give information about changes in the electronic states of the ligands. From the ATR-FUV spectra, the coordination numbers between Li+ and monoglyme, diglyme, triglyme, and PEG400 were determined to be 4, 5, 6, and 5, respectively. Our results indicate that Li+ is coordinated only by the ligands rather than its counter-ions.</p>
