2: Two isomers of fluoroethylene-(CO 2) 2 observed using chirped-pulse Fourier-transform microwave spectroscopy]]>

摘要

Understanding structural changes during microsolvation of a solute by increasing numbers of CO2molecules provides a path towards improved models of supercritical CO2solvent properties. Microwave spectroscopic observations of fluoroethylene (FE) microsolvation by CO2give two FE-(CO2)2isomers, each with fragments similar to previously studied planar FE-CO2dimers. In each trimer, a second CO2is located above the FE plane, in a position not observed for FE-CO2. Current work on FE/CO2mixtures focuses on deconvoluting interleaved spectra in the microwave scan, aiming to identify FE-(CO2)3and other clusters, with patterns from at least five additional cluster spectra already identified.
