Abstract
The Front Cover shows how paraldehyde (C6H12O3) was prepared in low-temperature acetaldehyde ices exposed to energetic irradiation as proxies of galactic cosmic rays. By utilizing vacuum ultraviolet photoionization reflectron time-of-flight mass spectrometry and isotopic substitution experiments, paraldehyde was identified in the gas phase during the temperature-programmed desorption process based on calculated adiabatic ionization energies and isomer-specific dissociative fragmentation patterns upon photoionization. More information can be found in the Research Article by R. C. Fortenberry, R. I. Kaiser and co-workers (DOI: 10.1002/cphc.202400837).
封面展示了如何在暴露于高能辐照的低温乙醛冰中制备副醛（C6H12O3），以此作为银河宇宙射线的替代物。通过利用真空紫外光离子化反射电子飞行时间质谱和同位素置换实验，根据计算出的绝热电离能和光离子化时特定异构体的解离碎片模式，确定了气相中副醛在温度编程解吸过程中的存在。更多信息可参阅 R. C. Fortenberry, R. I. I. 的研究文章。Fortenberry、R. I.Kaiser 及其合作者的研究文章中（DOI: 10.1002/cphc.202400837）。
