Exitationen

Exitationen is a plural noun that refers to instances or processes of excitation across various scientific disciplines. The term is used to describe the act of stimulating a system or the resulting excited states, such as electrons promoted to higher energy levels, vibrational or rotational excitations in molecules, or collective excitations in solids. In many contexts, however, editors prefer more common German terms like Anregung or Erregung.

Etymology and usage note: Exitationen derives from the root excitation, influenced by Latin and English terminology. In contemporary German technical writing, Exitationen appears comparatively rarely and is often regarded as archaic or borrowed. The more standard equivalents are Anregungen (stimulations) in physics and chemistry, or Erregungen (excitations) in physiology and neuroscience. When Exitationen is encountered, it is typically in historical texts, cross-linguistic references, or specialized jargon.

Domains and meanings:

- Physics and chemistry: electronic, vibrational, and rotational excitations; excitations in solids such as phonons or magnons; transitions to higher energy states within atoms or molecules.

- Neurophysiology and biology: nerve or muscle excitation, though contemporary terminology more commonly uses Erregung or Reizleitung rather than Exitationen.

- Electrical engineering: excitation signals that drive devices or circuits; in German literature these are more often described as Anregungen rather than Exitationen.
