Bust of Schrödinger, in the courtyard arcade of the main building, University of Vienna, Austria Erwin Rudolf Josef Alexander Schrödinger (UK: / ˈ ʃ r ɜː d ɪ ŋ ər, ˈ ʃ r oʊ d ɪ ŋ ər /, US: / ˈ ʃ r oʊ d ɪ ŋ ər /; [3] German: [ˈɛɐ̯vɪn ˈʃʁøːdɪŋɐ]; 12 August 1887 – 4 January 1961), sometimes written as Schroedinger or Schrodinger, was a Nobel Prize–winning ...
The Bohr model was based on the assumed quantization of angular momentum according to = =. According to de Broglie, the electron is described by a wave, and a whole number of wavelengths must fit along the circumference of the electron's orbit: n λ = 2 π r . {\displaystyle n\lambda =2\pi r.}
Much insight in quantum mechanics can be gained from understanding the closed-form solutions to the time-dependent non-relativistic Schrödinger equation.It takes the form
Quantum superposition is a fundamental principle of quantum mechanics that states that linear combinations of solutions to the Schrödinger equation are also solutions of the Schrödinger equation.
By this time the Ernest Rutherford model of the atom had been published, [21] [22] but much of the discussion involving atomic structure revolved around the quantum model of Arthur Haas in 1910. Also, at the Solvay Congress in 1911 Hendrik Lorentz suggested after Einstein's talk on quantum structure that the energy of a rotator be set equal to nhv.

The current theoretical model of the atom involves a dense nucleus surrounded by a probabilistic "cloud" of electrons. Atomic theory is the scientific theory that matter is composed of particles called atoms. The definition of the word "atom" has changed over the years in response to scientific discoveries.
Only the (internal) atomic vibrations enter the problem. Further, for molecules larger than triatomic ones, it is quite common to introduce the harmonic approximation, which approximates the potential energy surface as a quadratic function of the atomic displacements. This gives the harmonic nuclear motion Hamiltonian.
