= Rotational spectroscopy
{wiki=Rotational_spectroscopy}
Rotational spectroscopy is a technique used to study the rotational motions of molecules by measuring the electromagnetic radiation they emit or absorb, particularly in the microwave region of the spectrum. This method provides detailed information about the molecular structure, including bond lengths and angles, as well as the moments of inertia of the molecules. The fundamental principle behind rotational spectroscopy is based on the fact that molecules can rotate about their axes and that these rotational transitions correspond to specific energy levels.
