在锂 perchlorate/4-methoxymethyl-ethylene 碳酸盐(MEC ) 的溶液的 Solvation 相互作用和离子协会被使用学习了红外线并且拉曼系列作为锂的集中的功能高氯酸盐。切开戒指变丑乐队和戒指醚拉长乐队的羰基的不对称的拉长乐队,和变化建议应该在 Li+ 和溶剂分子之间有一个强壮的相互作用,并且 solvation 的地点应该是羰基组的氧原子。Li+ 的明显的 solvation 数字被使用乐队试穿技术计算。solvation 数字与增加 LiClO4/MEC 答案的集中从 3.3 ~ 1.1 被减少。在另一方面,为 ClO 的乐队试穿 ? 4 乐队揭示了接触离子对,和免费 ClO 的存在 ? 在集中的溶液的 4 阴离子。
Solvation interaction and ion association in solutions of lithium perchlorate/4-methoxymethyl-ethylene carbonate (MEC) have been studied by using Infrared and Raman spectra as a function of concentration of lithium perchlorate. The splitting of ring deformation band and ring ether asymmetric stretching band, and the change of carbonyl stretching band suggest that there should be a strong interaction between Li^+ and the solvent molecules, and the site of solvation should be the oxygen atom of carbonyl group. The apparent solvation number of Li^+ was calculated by using band fitting technique. The solvation number was decreased from 3.3 to 1.1 with increasing the concentration of LiClO4/MEC solutions. On the other hand, the band fitting for the ClO4^- band revealed the presence of contact ion pair, and free ClO4^- anion in the concentrated solutions.
