First solvation shell
WebSep 18, 2024 · Our simulations reveal significant differences in the solvation structure and dynamical properties of Na + and K + compared to Li +. We find that, in contrast to Li + which exhibits a well-defined first solvation shell, the larger Na+ and K+ ions show more disordered and flexible solvation structures. WebThe FT-EXAFS spectrum of [1 m Zn(TFSI) 2 + 10 m LiTFSI] in H 2 O shows a dominant Zn−O interaction at about 1.6 Å and some weak interactions at longer distances, indicating that the solvation structure of Zn 2+ is mostly limited to the first shell, which corresponds to the first and the strongest peak (Zn−O bond). 30 In addition, the CN ...

Oxygen, hydrogen, and chlorine atoms are represented by red, blue, and cyan colors, respectively. WebNov 9, 2001 · For singly charged ions such as Na + and K +, the first solvation shell would thus appear sufficient to reproduce the essential thermodynamics of solvation ( 2 ). Gas phase studies have shown that in the case of singly charged ions, the first solvation shell is indeed effective at shielding the charge from the remaining solvent molecules.
