On the Quantum Theory of Line-Spectra, Part 1 and 2

"On the Quantum Theory of Line-Spectra" by Niels Bohr (1918) is a series of papers that extend Bohr's quantum theory of the atom. In Parts 1 and 2, Bohr refines his model of quantized energy levels to explain the discrete wavelengths of light emitted by atoms, particularly hydrogen. He introduces concepts like stationary states and quantum jumps, where electrons transition between energy levels, emitting or absorbing photons. This work was critical in advancing the understanding of atomic spectra and laid the groundwork for modern quantum mechanics. Read more
