two-photon excitation

https://doi.org/10.1351/goldbook.T06541
Excitation resulting from successive or simultaneous absorption of two photons by an atom or molecular entity. This term is used for successive absorption only if some of the @E02250@ of the first photon remains in the atom or molecular entity before absorption of the second photon. The simultaneous two-photon absorption can also be called @B00668@.
