Rotational transitions refer to changes in the rotational energy levels of a molecule. Molecules can rotate around their axes, and these rotations correspond to specific energy levels governed by quantum mechanics. When a molecule absorbs or emits energy, it can transition between these different rotational levels. In more detail: 1. **Molecular Rotations**: Molecules can be thought of as rigid rotors.
