Understanding structural changes during microsolvation of a solute by increasing numbers of CO₂ molecules provides a path towards improved models of supercritical CO₂ solvent properties. Microwave spectroscopic observations of fluoroethylene (FE) microsolvation by CO₂ give two FE-(CO₂)₂ isomers, each with fragments similar to previously studied planar FE-CO₂ dimers. In each trimer, a second CO₂ is located above the FE plane, in a position not observed for FE-CO₂. Current work on FE/CO₂ mixtures focuses on deconvoluting interleaved spectra in the microwave scan, aiming to identify FE-(CO₂)₃ and other clusters, with patterns from at least five additional cluster spectra already identified.

通过增加CO ₂分子数量来了解溶质微溶剂化过程中的结构变化，为改进超临界CO ₂溶剂特性模型提供了一条途径。微波光谱观察氟乙烯（FE）通过CO _2的微溶剂化得到两个FE-（CO ₂）₂异构体，每个异构体的片段与先前研究的平面FE-CO ₂二聚体相似。在每个微调器中，第二个CO ₂位于FE平面上方，处于FE-CO _2所没有观察到的位置。目前对FE / CO ₂混合物的研究重点是在微波扫描中对卷积交错光谱进行去卷积，旨在鉴定FE-（CO ₂）_3个和其他星团，至少已经确定了来自另外五个星团光谱的模式。
