Interactions of Matter with Radiation
In Sect. 8.2.1, we already had a look at the interaction of atoms and electromagnetic radiation. Specifically, the atomic spectra were used to obtain insights into the inner fabric of atoms and their energetic states. Importantly, the spectral data provided the experimental verification of theoretical models such as the atomic model by Bohr (Sect. 8.2.2) and the quantum mechanics of the hydrogen atom by the Schrödinger equation (Sect. 10.1).
