利用宽带啁啾脉冲傅里叶变换微波光谱技术，获得了(E)-1-氯-1,2-二氟乙烯的4个同位素体，以及(E)-1-氯-1,2-二氟乙烯与氩形成的配合物的2个同位素体在5.6 ~ 18.1 GHz波段的微波光谱。测定了氩原子在氟乙烯对称平面外的位置与相邻的氟原子和氯原子以及碳原子C-1双键末端的π电子密度发生最强烈的相互作用。正如之前研究的氩-2-氯-1,1-二氟乙烯配合物一样，氩原子与氟原子和氯原子的相互作用最强烈，无论它们是否位于相邻的位置。
The microwave spectra of four isotopologues of (E)-1-chloro-1,2-difluoroethylene, and additionally, the spectra of two isotopologues of the complex formed between argon and (E)-1-chloro-1,2-difluoroethylene are obtained in the 5.6–18.1 GHz region using broadband chirped pulse Fourier transform microwave spectroscopy. The argon atom is determined to occupy a position out of the symmetry plane of the haloethylene where it can interact most strongly with the fluorine atom and the chlorine atom located geminal to each other as well as the π electron density at the end of the double bond on carbon atom C-1. As in the previously studied argon-2-chloro-1,1-difluoroethylene complex, the argon atom interacts most strongly with a fluorine atom and the chlorine atom regardless of whether they are located geminal orcisto each other.
