Quantum Mechanics/Waves and Modes
< Quantum Mechanics
Many misconceptions about quantum mechanics may be avoided if some concepts of field theory and quantum field theory like "normal mode" and "occupation" are introduced right from the start. They are needed for understanding the deepest... |

A brief introduction to basis sets
In order to compute the energy we need to define mathematical functions for the orbitals. In the case of atoms we can simply use the solutions to the Schrödinger equation for the $\ce{H}$ atom as a starting point and find the best exponent for each function u... |
