The pure rotational fingerprints of molecules are typically in the technically challenging millimeter and submillimeter region. Here we will get familiar with a state-of-the-art spectrometer, which fulfills nowadays requirements of astronomers like high resolution and sensitivity to interpret their data, received for example from the Atacama Large Millimeter Array (ALMA). Technical details and methods are explained but special focus is on understanding and interpreting the composition and structure of rotational Fingerprints of the linear molecule OCS.
