在过去的五十多年里，化学物理和物理化学领域的研究主要旨在了解分子的量子特性。然而，高分辨率的振转电子光谱学一直局限于相对较小和简单的体系，因为对于大型和复杂的体系，平移和转动冷态样本尚未能大量制备。在这项研究中，我们展示了大型气相分子，即自由碱酞菁（FBPc）的高分辨率振转电子光谱结果。研究结果表明，缓冲气体冷却对于通过激光烧蚀引入的大分子可能是有效的。高分辨率电子光谱学，结合其他实验和理论研究，将有助于理解分子的量子特性。这些发现也为大分子的量子化学计算提供了指导。
高分辨率分子光谱为分子的量子特性提供了极有价值的见解，但由于难以制备大型和复杂体系的平移和转动冷态样本，高分辨率振转电子光谱在很大程度上一直局限于相对较小的体系。在这里，作者证明了缓冲气体冷却可能是获得大型气相分子高分辨率振转电子光谱结果的一种有效策略。
For over five decades, studies in the field of chemical physics and physical chemistry have primarily aimed to understand the quantum properties of molecules. However, high-resolution rovibronic spectroscopy has been limited to relatively small and simple systems because translationally and rotationally cold samples have not been prepared in sufficiently large quantities for large and complex systems. In this study, we present high-resolution rovibronic spectroscopy results for large gas-phase molecules, namely, free-base phthalocya-nine (FBPc). The findings suggest that buffer-gas cooling may be effective for large molecules introduced via laser ablation. High-resolution electronic spectroscopy, combined with other experimental and theoretical studies, will be useful in understanding the quantum properties of molecules. These findings also serve as a guide for quantum chemical calculations of large molecules. High-resolution molecular spectroscopy provides invaluable insight into the quantum properties of molecules, but high-resolution rovibronic spectroscopy has largely been limited to relatively small systems owing to the difficulty in preparing translationally and rotationally cold samples for large and complex systems. Here, the authors demonstrate that buffer-gas cooling may be an effective strategy to obtain high-resolution rovibronic spectroscopy results for large gas-phase molecules.
