The 12 pages that link to Photochemical reaction, each with the reason it gives.

• Chemical reactionBroader topic: It contrasts with transformations initiated chiefly by heat, mixing, or electrical input.

• PhotolysisNarrower topic: Photolysis is one pathway within the broader class of light-initiated chemical transformations.

• Quantum yieldRelated: Product quantum yield counts reacted molecules per absorbed photon, not emitted photons.

• Electrocyclic reactionRelated: Excitation changes electrocyclic orbital occupancy and can reverse the thermal rotation mode.

• CycloadditionRelated: Light can change orbital-symmetry rules and permit cycloadditions forbidden thermally.

• Pericyclic reactionRelated: Photoexcitation changes orbital occupancy and can reverse the symmetry permissions found under heat.

• Elementary reactionRelated: Light absorption can initiate elementary molecular events that differ from thermal steps.

• Nicéphore NiépceNarrower topic: Heliography records light through chemical changes in a coated surface.

• George PorterNarrower topic: The challenge of measuring light-driven reactions motivated Porter’s method development.

• Niels Ryberg FinsenRelated: Finsen proposed that short-wavelength light could produce effects in tissue through chemical action.

• View from the Window at Le GrasNarrower topic: The image depends on light changing the solubility of its bitumen coating.

• Forbidden mechanismRelated: Light can change electronic-state occupancy and permit pathways forbidden thermally.
