photodynamicsn.

Brit.

/ˌfəʊtə(ʊ)dʌɪˈnamɪks/, U.S.

/ˈˌfoʊdəˌdaɪˈnæmɪks/

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

Etymology: < photo- comb. form + dynamics n. Compare slightly later photodynamic adj.

The branch of science that deals with the energy of light, esp. in relation to its interaction with molecules. Also: the properties of a substance with regard to photochemical reactions and processes.

1934 Amer. Anthropologist 36 438 The constructive or nutritional action of the sun's rays were first prominently disclosed in the cure of rickets. This discovery..has greatly stimulated interest and research in biochemistry, photodynamics and cure by sunlight of other nutritional diseases like anemia.

1976 Science 15 Oct. 279/3 In the study of the photodynamics of a number of acid-base indicator dyes, we noted that virtually all of the indicators with the triphenylmethane structure displayed closely related transient bleaching behavior.
