Cryogenic ion trap vibrational spectroscopy paired with quantum chemistry currently represents the most generally applicable approach for the structural investigation of gaseous cluster ions that are not amenable to direct absorption spectroscopy. Here, we give an overview of the most popular variants of infrared action spectroscopy and describe the advantages of using cryogenic ion traps in combination with messenger tagging and vibrational predissociation spectroscopy. We then highlight a few recent studies that apply this technique to identify highly reactive ionic intermediates and to characterize their reactive sites. We conclude by commenting on future challenges and potential developments in the field.
低温离子阱振动光谱学与量子化学相结合，目前是研究不适于直接吸收光谱学的气态团簇离子结构的最通用方法。本文概述了最流行的红外作用光谱学变体，并描述了在与信息分子标记和振动预解离光谱学结合使用时低温离子阱的优势。然后，我们强调了一些最近应用该技术来识别高反应性离子中间体并对其反应部位进行表征的研究。最后，我们对该领域未来的挑战和潜在发展进行了评论。
