A fundamental key to unlocking the structure and the internal physics of molecules lies in understanding patterns in the colours of light that they absorb and emit. We obtain these patterns - the molecular spectrum - by probing the molecules with lasers, or with other light sources. Since the spectrum is a unique identifier for a particular molecule, we can determine important information about the composition of the atmosphere, or of astrophysical objects like comets, nebulae, stars, and the interstellar medium, by comparing spectra obtained from these objects to those obtained on Earth.

解开分子结构和内部物理的一个基本关键在于理解它们吸收和发射的光的颜色模式。我们通过用激光或其他光源探测分子来获得这些模式--分子光谱。由于光谱是特定分子的唯一标识符，因此我们可以通过比较从这些物体获得的光谱与在地球上获得的光谱来确定关于大气层或彗星、星云、恒星和星际介质等天体物理物体的组成的重要信息。
