2+2 photocycloaddition

Index 2+2 photocycloaddition

The photocycloaddition is a cycloaddition-type reaction – it generally entails the formation of new molecules by the reaction of two unsaturated molecules via two atoms from each molecule (hence ""). [1]

Cycloaddition

A cycloaddition is a pericyclic chemical reaction, in which "two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity." The resulting reaction is a cyclization reaction.

Excimer

An excimer (originally short for excited dimer) is a short-lived dimeric or heterodimeric molecule formed from two species, at least one of which has completely filled valence shell by electrons (for example, noble gases).

Excited state

In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum).
