This project is a concerted laboratory and astrophysics observational effort, using the upcoming Herschel satellite within its guaranteed time observations. Many molecules have their fingerprint-like spectra in the Terahertz frequency region which will be covered by Herschel for the first time with unprecedented sensitivity. Herschel will unfold the molecular complexity in the interstellar medium. The molecular richness of the sources originates from evaporation of molecules trapped in ice mantles and/or from gas phase chemical reactions, which can proceed only at relatively high temperatures. Results from this project will answer questions such as how complex molecules can be formed and exist in space, including the fascinating perspective on how life started on earth. For the interpretation of the observations laboratory spectroscopic studies are essential and will be carried out in a very systematic fashion. The aims and thus the joint program of this project are guided by two Herschel guaranteed time key scientific programs (HEXOS and PRISMAS) which have been developed by international consortia including the proposers and which have been approved recently by the Herschel Time Allocation Committee.

该项目是一致的实验室和天体物理学观察工作，在其保证的时间观察中使用即将推出的Herschel卫星。许多分子在Terahertz频率区域具有其指纹样光谱，该光谱将以前所未有的灵敏度首次被Herschel覆盖。 Herschel将展现星际介质中的分子复杂性。来源的分子丰富性起源于被困在冰壳中和/或气相化学反应中的分子的蒸发，这些反应只能在相对较高的温度下进行。该项目的结果将回答诸如如何形成复杂的分子并在太空中存在的问题，包括对生命如何在地球上开始的迷人观点。为了解释观察结果，实验室光谱研究至关重要，并且将以非常系统的方式进行。该项目的目的以及该项目的联合计划的指导下，由国际财团（包括提议者）开发的两个Herschel保证时间关键的科学计划（Hexos和Prismas），并已获得Herschel Time Atitocation委员会最近批准。
