Chirped Pulse Fourier Transform Spectroscopy (CP-FTS) is used in this project i) to record broad band spectra in the centimeter and millimeter wavelength ranges to help interpreting astrophysical observations within CRC 956 and ii) for fast excitation and data acquisition allowing to record time dependent signals which opens the possibility to study collision kinetics of spectrally identified molecules, e.g. NH3 + H2 and He. The laboratory emission spectrometer built in collaboration between B3, B4, D3 and project S shall serve as advanced receivers for future CP-FTS experiments.

啁啾脉冲傅立叶变换光谱（CP-FTS）在这个项目中使用i)记录厘米和毫米波长范围内的宽带光谱，以帮助解释CRC 956内的天体物理观测；ii)用于快速激发和数据采集，允许记录时间相关信号，这为研究光谱识别分子的碰撞动力学提供了可能，例如NH3 + H2和He。B3、B4、D3与S项目合作建设的实验室发射光谱仪将作为未来CP-FTS实验的先进接收器。
