在低温俘获实验中，利用带有氦和氖标记的红外预解离光谱对CHCl₂⁺双正离子的不同异构体进行了研究。结果表明，H - C - Cl₂⁺异构体在通过红外预解离光谱检测到的被俘获双正离子中占主要部分。其他可能的异构体，比如H - Cl - C₂⁺，会通过与氦缓冲气体的质子转移反应而减少，但是通过使用氖标记，有可能稳定H - Cl - C₂⁺的氖配合物，并在红外预解离实验中检测到它们。© 2014爱思唯尔有限公司。保留所有权利。
Different isomers of the CHCl2+ dications were studied using infrared predissociation spectroscopy with helium and neon tagging in a low-temperature trapping experiment. It is shown that H-C-Cl2+ isomers form the dominant portion of the trapped dications that were detected by IRPD spectroscopy. Other possible isomers, such as H-Cl-C2+, are depleted by a proton transfer reaction with the helium buffer gas but by using neon tagging it was possible to stabilize the neon complexes of H-Cl-C2+ and detect them in the IRPD experiment.
