photochemistryn.

Brit.

/ˌfəʊtə(ʊ)ˈkɛmᵻstri/, U.S.

/ˌfoʊdəˈkɛməstri/

Origin: Formed within English, by compounding. Etymons: photo- comb. form, chemistry n.

Etymology: < photo- comb. form + chemistry n. Compare slightly earlier photochemical adj. and photochemically adv.

The branch of chemistry that deals with the effects on molecules and their reactions of the absorption of energy from light (or from electromagnetic radiation of a similar wavelength to light). Also: the photochemical properties of a substance.
