paritychanging
Paritychanging is the notion of changing the parity of a system or state, where parity is the property of an object or a mathematical state under inversion. In physics, parity refers to how a wavefunction or an arrangement behaves when spatial coordinates are inverted through the origin. A parity-changing process maps a state with a given parity to a state of opposite parity.
In quantum mechanics, a process that does not conserve parity is called parity-violating or parity-changing. The
In spectroscopy and molecular physics, many electric-dipole transitions require a change in parity. For atoms and
In information technology and data transmission, parity refers to a simple redundancy check. A parity-changing operation
