Infrared spectroscopic studies of molecules, nano-, and micro-particles in artificial atmospheres

第一个研究课题集中在气相分子的高分辨率分子光谱学。除其他事项外，追求的基本目标，如通过全球超势面的分子内动力学的阐明，光谱测量数据和分子参数，如线位置，带中心，线强度，压力加宽系数和压力位移系数的提供，也为数据库，如Hitran。在这里，重点是分子二氧化氯，臭氧，三氟甲烷及其不同的同位素体和同位素异构体。计划中的工作也有应用参考，例如地球，其他行星，其卫星和星际空间大气中气体的物理化学。在第二个研究课题中，将对以二氧化碳为主的火星大气进行实验模拟和红外光谱测量。目标和实验能力都远远超出了初步项目的目标和能力。与此同时，还提供了分辨率提高一倍以上的高分辨率傅里叶变换红外光谱仪，以及具有200米光程的长光程池，在初步项目中开发的温度非常稳定的可回火气体池，以及各种辐射热计和罕见的远红外高性能锗铜探测器。

The first research topic focuses on high-resolution molecular spectroscopy of molecules in the gas phase. Among other things, fundamental goals are pursued, such as the elucidation of intramolecular dynamics via global hyperpotential surfaces, the provision of spectroscopic measurement data and molecular parameters, such as line positions, band centers, line strengths, pressure broadening coefficients and pressure shift coefficients, also for databases such as Hitran. Here, the focus is on the molecules chlorine dioxide, ozone, trifluoromethane with their diverse isotopologues and isotopomers. The planned work also has application references, such as the physical chemistry of gases in the atmospheres of Earth, other planets, their moons, and in interstellar space. In the second research topic, an experimental simulation and IR spectrometric measurement of the CO2-dominated atmosphere of Mars will be performed. Both the objectives and the experimental capabilities go far beyond those of the preliminary project. In the meantime, a high-resolution FTIR spectrometer with more than doubled resolving power is available, as well as a long-path cell with 200 m optical path, an extraordinarily temperature-stable temperable gas cell, which was developed in the preliminary project, as well as various bolometers and a rare high-performance germanium-copper detector in the far infrared.
