The class of active components of the group of β‐lactam antibiotics is very important for several fields and applications, although their stability and radiation reactivity properties are not yet well understood. We have studied the interaction of an important building block species, the 2‐azetidinone (C₃H₅NO) molecule, with monochromatic VUV (synchrotron radiation) photons in the 9.5–21.5 eV range, using time‐of‐flight mass spectrometry (TOF‐MS), electron‐ion coincidence (PEPICO), and high‐level theory methods.

2-氮杂环丁酮（C3H5NO）的分子结构和VUV诱导的离子解离动力学研究

尽管尚未很好地了解β-内酰胺类抗生素的活性成分的稳定性和辐射反应性，但它​​们在几个领域和应用中都非常重要。我们使用飞行时间质谱法研究了一种重要的构建基团物质2-氮杂环丁酮（C ₃ H ₅ NO）分子与9.5-21.5 eV范围内的单色VUV（同步辐射）光子之间的相互作用（ TOF-MS），电子离子符合（PEPICO）和高级理论方法。
