    en.wikipedia.org/wiki/2,2-Dimethoxy-2-phenylace...

    2,2-Dimethoxy-2-phenylacetophenone is a photoinitiator, which is used to initialize radical polymerization e.g. in the preparation of acrylate polymers. [1] Under the influence of light the molecule will form radicals which initiate the radical polymerization. It can also be used as an initiator in the process of making an integrated circuit.

  3. Photochemical action plots - Wikipedia

    en.wikipedia.org/wiki/Photochemical_action_plots

    Photochemical action plots are a scientific tool used to understand the effects of different wavelengths of light on photochemical reactions.The methodology involves exposing a reaction solution to the same number of photons at varying monochromatic wavelengths, monitoring the conversion or reaction yield of starting materials and/or reaction products.

  4. Photoinitiator - Wikipedia

    en.wikipedia.org/wiki/Photoinitiator

    Irgacure 819 (BAPO Bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide) is a Norrish type photoinitiator used in polymerization processes like two-photon Polymerization. [7] When exposed to light it forms four radicals (2, 3, 5) per decomposed molecule (1), making it highly efficient in initiating polymerization.

  5. Acetophenone - Wikipedia

    en.wikipedia.org/wiki/Acetophenone

    Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:

  7. 2,4'-dihydroxyacetophenone dioxygenase - Wikipedia

    en.wikipedia.org/wiki/2,4'-dihydroxyacetophenone...

    In enzymology, a 2,4'-dihydroxyacetophenone dioxygenase (EC 1.13.11.41) is an enzyme that catalyzes the chemical reaction. 2,4'-dihydroxyacetophenone + O 2 4-hydroxybenzoate + formate. Thus, the two substrates of this enzyme are 2,4'-dihydroxyacetophenone and O 2, whereas its two products are 4-hydroxybenzoate and formate.

    en.wikipedia.org/wiki/Two-photon_absorption

    Schematic of energy levels involved in two photons absorption. In atomic physics, two-photon absorption (TPA or 2PA), also called two-photon excitation or non-linear absorption, is the simultaneous absorption of two photons of identical or different frequencies in order to excite an atom or a molecule from one state (usually the ground state), via a virtual energy level, to a higher energy ...
