  • Excitation | electron transitions, energy levels spectroscopy . . .
    Excitation, in physics, the addition of a discrete amount of energy (called excitation energy) to a system—such as an atomic nucleus, an atom, or a molecule—that results in its alteration, ordinarily from the condition of lowest energy (ground state) to one of higher energy (excited state)
  • Exciton - Wikipedia
    An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb force resulting from their opposite charges
  • EXCITATION | definition in the Cambridge English Dictionary
    EXCITATION meaning: 1 the process of making something, for example a particle or a cell, more active: 2 the process… Learn more
  • EXCITATION definition and meaning | Collins English Dictionary
    Excitation is the act of making something vibrate If the ship's vibration is caused by the propeller, the excitation may be reduced by changing the propeller The simplest form of excitation is to pluck a stretched wire by hand so that it vibrates
  • What is excitation and ionization? - Physics Network
    Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule
  • Excitation | definition of excitation by Medical dictionary
    excitation An MRI term for the delivery—i e , induction or transfer—of energy into spinning nuclei via radio-frequency pulse(s), which bumps the nuclei into a higher energy state By producing a net transverse magnetisation, an MRI system can evoke a response from the excited system
  • EXCITATION Definition Meaning - Merriam-Webster

  • Excitation - (Principles of Physics IV) - Vocab, Definition . . . - Fiveable
    Excitation refers to the process by which an electron in an atom absorbs energy and transitions from a lower energy state to a higher energy state This phenomenon is crucial in understanding how multi-electron atoms behave, as the interactions and energy levels of these electrons determine the atom's overall properties
  • What does Excitation mean? - Definitions. net
    Excitation generally refers to the state of being energized, stimulated, activated or aroused This term is often used in various fields like physics, chemistry, physiology, psychology, and electronics, often with slightly different but related meanings
  • Excitation and Ionisation - PhysicsA-Level Revision - Revision Science
    Excitation is the result of energy being given to an electron moving it to a higher energy level It will still orbit the nucleus, unless the electron energy level is greater than the ionisation energy level of the atom
