我们从结构化学和分析化学的角度研究了水中二氧化碳的反对称伸缩基本原理 nu3 产生的红外吸收带，(CO2)-C-12 为 2342.9 cm-1，(CO2-C-13) 为 2277.7 cm-1。该带的位置仅与蒸气值偏移 6 cm-1，表明水分子和溶解的二氧化碳之间不存在氢键。 nu3 谱带具有良好的分析潜力，可用于水中二氧化碳的测定。我们还研究了碳酸根和碳酸氢根离子水溶液的红外波段的分析用途。
We have studied the infrared absorption band due to the antisymmetric stretching fundamental, nu3, of carbon dioxide in water at 2342.9 cm-1 for (CO2)-C-12 and 2277.7 cm-1 for (CO2-C-13), from the point of view of structural and analytical chemistry. The position of this band is shifted by only 6 cm-1 from the vapour value, indicating the absence of hydrogen bonding between water molecules and the dissolved carbon dioxide. The nu3 band has good analytical potential and may be used for the determination of carbon dioxide in water. We have also examined the analytical use of the infrared bands of aqueous carbonate and bicarbonate ions.
