Hydrogen Dichloride Radical: Infrared Detection through the Matrix Isolation Technique

摘要

When hydrogen chloridendash;chlorinendash;argon mixtures are passed through a glow discharge and the products are condensed at 14deg;K, two conspicuous infrared absorptions at 956 and 696 cmminus;1result. Concentration dependence of intensities, isotopic labeling, and forcehyphen;field calculations lead to assignment of these bands to hydrogen dichloride. The force field calculated supports a linear, centrosymmetriclpar;Dinfin;hrpar;structure with hydrogen bond strength apparently comparable to or exceeding those attributed to HCl2minus;in various crystals.
