unidad atómica

unidad atómica

A system of non-SI units used in quantum chemistry to simplify calculations and mathematical expressions. The definitions of atomic units include physical constants (like the speed of light , the rest mass of the electron, and other quantities that never change), so that all constants drop out of expressions when atomic units are used.
