Laboratory spectra of molecular anions are largely missing because they are hard to measure. This project uses action spectroscopy in ion traps to open the door in this direction. Rotational spectra of small anions shall help to find such species with radio observations. Vibrational spectra of polycyclic aromatic hydrocarbons (PAHs) are potential carriers of the unidentified infrared bands (UIRs) and in the era of the James Webb telescope (JWST) spectra of anionic PAHs may turn into a diagnostic tool for the different interstellar environments (habitats) in close and distant star forming regions.

分子阴离子的实验室光谱在很大程度上是缺失的，因为它们很难测量。这个项目在离子阱中使用作用光谱学来打开这个方向的大门。小阴离子的旋转光谱将有助于通过射电观测发现这些物种。多环芳烃（PAHs）的振动光谱是未知红外波段（UIR）的潜在载体，在詹姆斯韦伯望远镜（JWST）时代，多环芳烃的阴离子振动光谱有可能成为诊断近、远星星形成区不同星际环境（生境）的工具。
