valikureeglid
Valikureeglid, often translated as "selection rules," are a fundamental concept in various scientific disciplines, particularly in quantum mechanics and spectroscopy. These rules dictate which transitions between energy levels of a system are allowed or forbidden based on fundamental conservation laws and symmetries.
In quantum mechanics, valikureeglid arise from the properties of the wavefunctions describing the initial and final
Violations of these strict selection rules can occur under certain conditions. For instance, magnetic dipole transitions
