Here we discuss the reaction products of laser ablated alkali chlorides and elemental chlorine. Salt ablation using this technique combined with matrix-isolation spectroscopy allows for the formation and characterization of novel anionic species. The laser ablation of solid MCl with M = Cs, Rb, and K in the presence of Cl₂ produced free [Cl₃]⁻ ions which were isolated in solid noble-gas matrices. For M = Cs, Rb, K, and Na, the ion pairs M⁺[Cl₃]⁻ are the main reaction products. Trends in the formation and bonding of these trichloride anions will be discussed. In contrast to the trifluoride analogues, the isolated ion pairs M⁺[Cl₃]⁻ feature a systematic distortion due to metal coordination.

游离线性[Cl ₃ ] ^-和一系列三氯化碱的基质分离和比较远红外研究

在这里，我们讨论激光烧蚀的碱金属氯化物和元素氯的反应产物。使用这种技术与基质分离光谱相结合的盐消融技术可以形成和表征新型阴离子物质。在Cl ₂存在下，用M = Cs，Rb和K对固体MCl进行激光烧蚀产生了游离的[Cl ₃ ] ^-离子，这些离子在固体稀有气体基质中分离出来。对于M = Cs，Rb，K和Na，离子对M ⁺ [Cl ₃ ] ^-是主要的反应产物。将讨论这些三氯化物阴离子的形成和结合趋势。与三氟化物类似物相比，分离的离子对M ⁺ [Cl ₃ ]⁻由于金属配位而导致系统失真。
