Excited state in physics refers to a state of a system that has higher energy than the ground state. When an atom, molecule, or nucleus absorbs energy, it can undergo a transition to a higher energy state, which is known as the excited state.
Atomic Excited States
Atoms have discrete energy levels due to the quantization of energy in quantum mechanics. When an electron in an atom absorbs energy, it moves to a higher energy level, resulting in the atom being in an excited state. Electrons can jump between different energy levels by either absorbing or emitting photons.
Molecular Excited States
Molecules can also exist in excited states when they absorb energy. In molecules, the excitation typically involves the promotion of electrons to higher energy molecular orbitals. This can lead to the molecule exhibiting different chemical properties compared to its ground state.
Nuclear Excited States
Nuclei can also be in excited states when they have absorbed energy. Nuclear excited states are important in nuclear reactions and decay processes. Excited nuclei can emit gamma rays as they transition back to their ground state.
Excited states play a crucial role in various physical and chemical processes. They are involved in phenomena such as fluorescence, phosphorescence, and photochemistry. Understanding excited states is essential in fields such as spectroscopy, quantum mechanics, and materials science.
In summary, excited states represent higher energy states of systems such as atoms, molecules, and nuclei. They are characterized by the absorption of energy, leading to transitions to higher energy levels. Excited states are fundamental in the study of the behavior of matter at the microscopic level.
