Two-photon absorption (TPA) is the absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy electronic state.
Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.
Uranium is a chemical element with symbol U and atomic number 92.
Uranium glass is glass which has had uranium, usually in oxide diuranate form, added to a glass mix before melting for coloration.
The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula.
Vibronic spectra involve simultaneous changes in the vibrational and electronic energy states of a molecule.
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
