【摘要】 运用衰减全反射二维相关傅立叶变换红外光谱(ATR-2D-FTIR),以浓度为外扰因素,对乙腈(CH3CN)-水(H2O)-高氯酸钠(NaClO4)体系存在的一些弱作用力进行了研究．结果表明体系中乙腈的CH3与水分子OH存在相互作用．无机盐高氯酸钠的加入破坏了水分子的氢键结构,阴阳离子分别与水发生相互作用．Na+与氢键缔合水分子发生作用,而非自由水分子．无机盐的加入对体系中微观结构变化产生较大影响．更多还原

【Abstract】 A study of the weak interactions of acetonitrile-water-sodium perchlorate mixtures has been performed using attenuated total reflection two-dimensional FTIR spectroscopy (ATR-2D-FTIR). The results indicate that CH3 and OH in the mixtures have some weak interactions with each other. The inorganic salts, sodium perchlorate, disbond hydrogen-bonded structure of water. Some interactions have been found between ions of sodium perchlorate and water molecules. Cations of Na+ are combined with hydrogen-bonded water. Inorganic salts play an important role in changing the microstructure of the mixtures.更多还原
