Perfluoropropionic acid (CFCFC(O)OH) has been investigated with a focus on its complex structural properties. As a formal derivative of propanoic acid, the incorporation of fluorine atoms imparts unique structural features, including three distinct monomeric conformations and a dimeric structure. This study presents experimental findings, supported by computational modeling, to explore these characteristics. The analysis includes an FTIR study of the isolated species in an Ar-cryogenic matrix and the low-temperature determination of its crystalline structure using single-crystal X-ray diffraction.
全氟丙酸（CFCFC(O)OH）已被研究，重点是其复杂的结构特性。作为丙酸的一种形式衍生物，氟原子的引入赋予了独特的结构特征，包括三种不同的单体构象和一种二聚体结构。本研究展示了实验结果，并得到计算模型的支持，以探索这些特性。分析包括对氩低温基质中分离物种的傅里叶变换红外光谱（FTIR）研究，以及使用单晶X射线衍射对其晶体结构进行低温测定。
