energiataseme
Energiataseme is a term used in physics and chemistry to refer to the discrete energy states that a quantum system can occupy. In bound systems such as atoms, molecules, or nuclei, the allowed energies form a set of distinct levels rather than a continuous range. Each level is associated with a wavefunction that describes the probability distribution of the system’s properties, and the levels are often labeled by quantum numbers and symmetry properties. The population of levels at a given temperature follows statistical rules, with lower-energy states generally more populated than higher ones.
Transitions between energy levels are central to many phenomena. When a system absorbs or emits a photon
In molecules, electronic energy levels are accompanied by vibrational and rotational sublevels, producing rich spectra (vibronic
