<SUP>1</SUP > H 和 <SUP>13</SUP > C NMR 化学移动决心与房间温度调查丙酮的相互作用离子的液体 1-hexyl-3- methylimidazolium 溴化物[C <SUB>6</SUB > mim ] 在各种各样的鼹鼠部分的 Br。在氢原子核并且有丙酮集中的碳原子核的化学移动的变化显示了在离子的液体的阴离子和丙酮的甲基质子之间的氢债券的形成。NMR 结果在对 ab initio 的好同意是计算结果。
^1H and ^13C NMR chemical shifts were determined to investigate the interactions of acetone with a room temperature ionic liquid 1-hexyl-3- methylimidazolium bromide [C6mim]Br at various mole fractions. Changes in chemical shifts of hydrogen nuclei and of carbon nuclei with the acetone concentration indicated the formation of hydrogen bond between anion of the ionic liquid and methyl protons of acetone. The NMR results were in good agreement with the ab initio computational results.
