{wiki=Microwave_spectroscopy}
Microwave spectroscopy is a technique used to study the interactions of molecules with microwave radiation. It is primarily concerned with the rotational energy levels of molecules, which correspond to transitions between different rotational states. Microwave spectroscopy involves exposing a sample to microwave radiation and measuring the absorption or emission of this radiation as the molecules transition between their rotational states. The technique takes advantage of the fact that different molecules have unique rotational spectra, allowing researchers to identify and characterize them based on their rotational transitions.
