Abstract The microwave spectra of four isotopologues of (E)-1,3,3,3-tetrafluoropropene, which has been proposed as a refrigerant alternative with a low global warming potential and also finds use as a foaming agent, and additionally the spectra of four isotopologues of the complex formed between argon and (E)-1,3,3,3-tetrafluoropropene are obtained in the 5.3 – 21.1 GHz region using a combination of broadband chirped pulse and Balle-Flygare cavity Fourier transform microwave spectroscopy. The argon atom is determined to occupy a position out of the symmetry plane of the tetrafluoropropene where it can interact most strongly with the in-plane fluorine atom of the fluoromethyl group and carbon atom C1. This contrasts to the previously studied argon-2,3,3,3-tetrafluoropropene complex where the argon atom interacts most strongly with an out-of-plane fluorine atom and that attached to the olefinic carbon.

(E)-1,3,3,3-四氟丙烯及其与氩原子配合物的微波光谱和分子结构

摘要 (E)-1,3,3,3-四氟丙烯 (E)-1,3,3,3-四氟丙烯的四种同位素体的微波光谱，已被提议作为一种具有低全球变暖潜能值的制冷剂替代品，也可用作发泡剂，此外还有使用宽带啁啾脉冲和 Balle-Flygare 腔傅里叶变换微波光谱的组合，在 5.3 – 21.1 GHz 区域获得了氩和 (E)-1,3,3,3-四氟丙烯之间形成的复合物的四种同位素体。氩原子被确定占据四氟丙烯对称平面之外的位置，在该位置它可以与氟甲基基团的平面内氟原子和碳原子C1最强烈地相互作用。这与之前研究的 argon-2,3,3 形成对比，
