Virtual state

Source: Wikipedia, the free encyclopedia.
For the metastable state of a certain class of Feshbach resonance, see Feshbach resonance § Unstable state.

Energy-level diagram showing the states involved in Raman spectra, including virtual energy states.

In

quantum physics, a virtual state is a very short-lived, unobservable quantum state.[1]

In many quantum processes a virtual state is an intermediate state, sometimes described as "imaginary"

non-linear optics generally,[5] various types of photochemistry,[13] and nuclear processes.[14]
