The Schrödinger wave equation, which serves this purpose, is not something that can be rigorously derived from first principles. Like many other instances in physics, it is usually postulated and tested against experiments; its successes then justify its acceptance.
Take the Schrodinger equation, that is intrinsically complex, with complex 2-part solutions, −~2 2m ∂2ψ(x,t) ∂x2 + V(x,t)ψ(x,t) = i~ ∂ψ(x,t) ∂t, and its expectation value that yields the conservation of energy equation. hψ|K˜|ψi+hψ|V|ψi = hψ|Eψ˜ |i The potential in the above equation is real, for now.

The Schrödinger Equation. H = E. Introduction. the basic Schrödinger equation. H is the molecular Hamiltonian, and is an operator, think of it as a special type of function that describes all the internal interactions occurring in a molecule, for example, electron-electron interactions.
The Schrödinger Equation and its Interpretation. In this lecture you will learn: Schrödinger equation: the time-dependent form. Schrödinger equation: the probabilistic interpretation. Breakdown of determinism in quantum physics. The Quantum Physics of Photons.
Schrödinger Equation: The Time-Independent Form In this lecture you will learn: • Schrödinger equation –the time-independent form • Particle in an infinite potential well • Quantum mechanical tunneling
CHAPTER OVERVIEW. 9: Numerical Solutions for Schrödinger's Equation. Numerically solving the Schrödinger equation is a complex problem that stems from the large number of points needed on a grid and the requirement to satisfy boundary conditions.
