excimer
Transient bonded pair
An excimer is a molecule that exists only in an excited electronic state—it forms when atoms bond during excitation but falls apart when the energy dissipates.
The term blends "excited" and "dimer." Excimer lasers exploit this property, producing intense ultraviolet light used in eye surgery, semiconductor manufacturing, and dermatology: The LASIK procedure uses an excimer laser to reshape the cornea.
