WebThe Onsager Reaction Field and Vibrational Solvatochromism. The nitrile stretch is known to exhibit vibrational solvatochromism ( 18 , 42 – 44 ). In non-hydrogen-bonding systems, the transition frequency of the vibrational chromophore will shift based on the polarity of the solvating medium. Webconcentrated electrolyte solutions can be derived in terms of the Onsager coe cients, without involving any extrathermodynamic assumptions. By demonstrating it for the case of PEO-LiTFSI system, this work opens the door to calibrating molecular dynamics (MD) simulations via reproducing the Bruce-Vincent transference
